For example lets say there are two files\n     * '/local/src/content/file1.ts'\n     * '/shared/components/contracts/src/content/protocols/file2.ts'\n     * After bundling content of '/shared/components/contracts/src' will be merged with '/local/src' so\n     * if file1 has the following import 'import {x} from \"./protocols/file2\"' it will be resolved successfully in runtime.\n     * 'rootDirs' provides the way to tell compiler that in order to get the whole project it should behave as if content of all\n     * root dirs were merged together.\n     * I.e. for the example above 'rootDirs' will have two entries: [ '/local/src', '/shared/components/contracts/src' ].\n     * Compiler will first convert './protocols/file2' into absolute path relative to the location of containing file:\n     * '/local/src/content/protocols/file2' and try to load it - failure.\n     * Then it will search 'rootDirs' looking for a longest matching prefix of this absolute path and if such prefix is found - absolute path will\n     * be converted to a path relative to found rootDir entry './content/protocols/file2' (*). As a last step compiler will check all remaining\n     * entries in 'rootDirs', use them to build absolute path out of (*) and try to resolve module from this location.\n     */\n    function tryLoadModuleUsingOptionalResolutionSettings(extensions, moduleName, containingDirectory, loader, failedLookupLocations, state) {\n        if (moduleHasNonRelativeName(moduleName)) {\n            return tryLoadModuleUsingBaseUrl(extensions, moduleName, loader, failedLookupLocations, state);\n        }\n        else {\n            return tryLoadModuleUsingRootDirs(extensions, moduleName, containingDirectory, loader, failedLookupLocations, state);\n        }\n    }\n    function tryLoadModuleUsingRootDirs(extensions, moduleName, containingDirectory, loader, failedLookupLocations, state) {\n        if (!state.compilerOptions.rootDirs) {\n            return undefined;\n        }\n        if (state.traceEnabled) {\n            trace(state.host, ts.Diagnostics.rootDirs_option_is_set_using_it_to_resolve_relative_module_name_0, moduleName);\n        }\n        var candidate = ts.normalizePath(ts.combinePaths(containingDirectory, moduleName));\n        var matchedRootDir;\n        var matchedNormalizedPrefix;\n        for (var _i = 0, _a = state.compilerOptions.rootDirs;

For illustrative purposes, the following intermediate\n// language is used to define this intermediate representation:\n//\n//  .nop                            - Performs no operation.\n//  .local NAME, ...                - Define local variable declarations.\n//  .mark LABEL                     - Mark the location of a label.\n//  .br LABEL                       - Jump to a label. If jumping out of a protected\n//                                    region, all .finally blocks are executed.\n//  .brtrue LABEL, (x)              - Jump to a label IIF the expression `x` is truthy.\n//                                    If jumping out of a protected region, all .finally\n//                                    blocks are executed.\n//  .brfalse LABEL, (x)             - Jump to a label IIF the expression `x` is falsey.\n//                                    If jumping out of a protected region, all .finally\n//                                    blocks are executed.\n//  .yield (x)                      - Yield the value of the optional expression `x`.\n//                                    Resume at the next label.\n//  .yieldstar (x)                  - Delegate yield to the value of the optional\n//                                    expression `x`. Resume at the next label.\n//                                    NOTE: `x` must be an Iterator, not an Iterable.\n//  .loop CONTINUE, BREAK           - Marks the beginning of a loop. Any \"continue\" or\n//                                    \"break\" abrupt completions jump to the CONTINUE or\n//                                    BREAK labels, respectively.\n//  .endloop                        - Marks the end of a loop.\n//  .with (x)                       - Marks the beginning of a WithStatement block, using\n//                                    the supplied expression.\n//  .endwith                        - Marks the end of a WithStatement.\n//  .switch                         - Marks the beginning of a SwitchStatement.\n//  .endswitch                      - Marks the end of a SwitchStatement.\n//  .labeled NAME                   - Marks the beginning of a LabeledStatement with the\n//                                    supplied name.\n//  .endlabeled                     - Marks the end of a LabeledStatement.\n//  .try TRY, CATCH, FINALLY, END   - Marks the beginning of a protected region, and the\n//                                    labels for each block.\n//  .catch (x)                      - Marks the beginning of a catch block.\n//  .finally                        - Marks the beginning of a finally block.\n//  .endfinally                     - Marks the end of a finally block.\n//  .endtry                         - Marks the end of a protected region.\n//  .throw (x)                      - Throws the value of the expression `x`.\n//  .return (x)                     - Returns the value of the expression `x`.\n//\n// In addition, the illustrative intermediate representation introduces some special\n// variables:\n//\n//  %sent%                          - Either returns the next value sent to the generator,\n//                                    returns the result of a delegated yield, or throws\n//                                    the exception sent to the generator.\n//  %error%                         - Returns the value of the current exception in a\n//                                    catch block.\n//\n// This intermediate representation is then compiled into JavaScript syntax. The resulting\n// compilation output looks something like the following:\n//\n//  function f() {\n//      var /*locals*/;\n//      /*functions*/\n//      return __generator(function (state) {\n//          switch (state.label) {\n//              /*cases per label*/\n//          }\n//      });\n//  }\n//\n// Each of the above instructions corresponds to JavaScript emit similar to the following:\n//\n//  .local NAME                   | var NAME;\n// -------------------------------|----------------------------------------------\n//  .mark LABEL                   | case LABEL:\n// -------------------------------|----------------------------------------------\n//  .br LABEL                     |     return [3 /*break*/, LABEL];\n// -------------------------------|----------------------------------------------\n//  .brtrue LABEL, (x)            |     if (x) return [3 /*break*/, LABEL];\n// -------------------------------|----------------------------------------------\n//  .brfalse LABEL, (x)           |     if (!(x)) return [3, /*break*/, LABEL];\n// -------------------------------|----------------------------------------------\n//  .yield (x)                    |     return [4 /*yield*/, x];\n//  .mark RESUME                  | case RESUME:\n//      a = %sent%;

A client can find the preferred size for some Drawables with\n     *     the {@link #getIntrinsicHeight} and {@link #getIntrinsicWidth} methods.\n     *\n     *     <li> The {@link #getPadding} method can return from some Drawables\n     *     information about how to frame content that is placed inside of them.\n     *     For example, a Drawable that is intended to be the frame for a button\n     *     widget would need to return padding that correctly places the label\n     *     inside of itself.\n     *\n     *     <li> The {@link #setState} method allows the client to tell the Drawable\n     *     in which state it is to be drawn, such as \"focused\", \"selected\", etc.\n     *     Some drawables may modify their imagery based on the selected state.\n     *\n     *     <li> The {@link #setLevel} method allows the client to supply a single\n     *     continuous controller that can modify the Drawable is displayed, such as\n     *     a battery level or progress level.  Some drawables may modify their\n     *     imagery based on the current level.\n     *\n     *     <li> A Drawable can perform animations by calling back to its client\n     *     through the {@link Callback} interface.  All clients should support this\n     *     interface (via {@link #setCallback}) so that animations will work.  A\n     *     simple way to do this is through the system facilities such as\n     *     {@link android.view.View#setBackgroundDrawable(Drawable)} and\n     *     {@link android.widget.ImageView}.\n     * </ul>\n     *\n     * Though usually not visible to the application, Drawables may take a variety\n     * of forms:\n     *\n     * <ul>\n     *     <li> <b>Bitmap</b>: the simplest Drawable, a PNG or JPEG image.\n     *     <li> <b>Nine Patch</b>: an extension to the PNG format allows it to\n     *     specify information about how to stretch it and place things inside of\n     *     it.\n     *     <li> <b>Shape</b>: contains simple drawing commands instead of a raw\n     *     bitmap, allowing it to resize better in some cases.\n     *     <li> <b>Layers</b>: a compound drawable, which draws multiple underlying\n     *     drawables on top of each other.\n     *     <li> <b>States</b>: a compound drawable that selects one of a set of\n     *     drawables based on its state.\n     *     <li> <b>Levels</b>: a compound drawable that selects one of a set of\n     *     drawables based on its level.\n     *     <li> <b>Scale</b>: a compound drawable with a single child drawable,\n     *     whose overall size is modified based on the current level.\n     * </ul>\n     *\n     * <div class=\"special reference\">\n     * <h3>Developer Guides</h3>\n     * <p>For more information about how to use drawables, read the\n     * <a href=\"{@docRoot}guide/topics/graphics/2d-graphics.html\">Canvas and Drawables</a> developer\n     * guide.

A key press\n     * starts with a key event with {@link #ACTION_DOWN}.  If the key is held\n     * sufficiently long that it repeats, then the initial down is followed\n     * additional key events with {@link #ACTION_DOWN} and a non-zero value for\n     * {@link #getRepeatCount()}.  The last key event is a {@link #ACTION_UP}\n     * for the key up.  If the key press is canceled, the key up event will have the\n     * {@link #FLAG_CANCELED} flag set.\n     * </p><p>\n     * Key events are generally accompanied by a key code ({@link #getKeyCode()}),\n     * scan code ({@link #getScanCode()}) and meta state ({@link #getMetaState()}).\n     * Key code constants are defined in this class.  Scan code constants are raw\n     * device-specific codes obtained from the OS and so are not generally meaningful\n     * to applications unless interpreted using the {@link KeyCharacterMap}.\n     * Meta states describe the pressed state of key modifiers\n     * such as {@link #META_SHIFT_ON} or {@link #META_ALT_ON}.\n     * </p><p>\n     * Key codes typically correspond one-to-one with individual keys on an input device.\n     * Many keys and key combinations serve quite different functions on different\n     * input devices so care must be taken when interpreting them.  Always use the\n     * {@link KeyCharacterMap} associated with the input device when mapping keys\n     * to characters.  Be aware that there may be multiple key input devices active\n     * at the same time and each will have its own key character map.\n     * </p><p>\n     * As soft input methods can use multiple and inventive ways of inputting text,\n     * there is no guarantee that any key press on a soft keyboard will generate a key\n     * event: this is left to the IME's discretion, and in fact sending such events is\n     * discouraged.  You should never rely on receiving KeyEvents for any key on a soft\n     * input method.  In particular, the default software keyboard will never send any\n     * key event to any application targetting Jelly Bean or later, and will only send\n     * events for some presses of the delete and return keys to applications targetting\n     * Ice Cream Sandwich or earlier.  Be aware that other software input methods may\n     * never send key events regardless of the version.  Consider using editor actions\n     * like {@link android.view.inputmethod.EditorInfo#IME_ACTION_DONE} if you need\n     * specific interaction with the software keyboard, as it gives more visibility to\n     * the user as to how your application will react to key presses.\n     * </p><p>\n     * When interacting with an IME, the framework may deliver key events\n     * with the special action {@link #ACTION_MULTIPLE} that either specifies\n     * that single repeated key code or a sequence of characters to insert.\n     * </p><p>\n     * In general, the framework cannot guarantee that the key events it delivers\n     * to a view always constitute complete key sequences since some events may be dropped\n     * or modified by containing views before they are delivered.  The view implementation\n     * should be prepared to handle {@link #FLAG_CANCELED} and should tolerate anomalous\n     * situations such as receiving a new {@link #ACTION_DOWN} without first having\n     * received an {@link #ACTION_UP} for the prior key press.\n     * </p><p>\n     * Refer to {@link InputDevice} for more information about how different kinds of\n     * input devices and sources

Multi-touch\n     * screens emit one movement trace for each finger.  The individual fingers or\n     * other objects that generate movement traces are referred to as <em>pointers</em>.\n     * Motion events contain information about all of the pointers that are currently active\n     * even if some of them have not moved since the last event was delivered.\n     * </p><p>\n     * The number of pointers only ever changes by one as individual pointers go up and down,\n     * except when the gesture is canceled.\n     * </p><p>\n     * Each pointer has a unique id that is assigned when it first goes down\n     * (indicated by {@link #ACTION_DOWN} or {@link #ACTION_POINTER_DOWN}).  A pointer id\n     * remains valid until the pointer eventually goes up (indicated by {@link #ACTION_UP}\n     * or {@link #ACTION_POINTER_UP}) or when the gesture is canceled (indicated by\n     * {@link #ACTION_CANCEL}).\n     * </p><p>\n     * The MotionEvent class provides many methods to query the position and other properties of\n     * pointers, such as {@link #getX(int)}, {@link #getY(int)}, {@link #getAxisValue},\n     * {@link #getPointerId(int)}, {@link #getToolType(int)}, and many others.  Most of these\n     * methods accept the pointer index as a parameter rather than the pointer id.\n     * The pointer index of each pointer in the event ranges from 0 to one less than the value\n     * returned by {@link #getPointerCount()}.\n     * </p><p>\n     * The order in which individual pointers appear within a motion event is undefined.\n     * Thus the pointer index of a pointer can change from one event to the next but\n     * the pointer id of a pointer is guaranteed to remain constant as long as the pointer\n     * remains active.  Use the {@link #getPointerId(int)} method to obtain the\n     * pointer id of a pointer to track it across all subsequent motion events in a gesture.\n     * Then for successive motion events, use the {@link #findPointerIndex(int)} method\n     * to obtain the pointer index for a given pointer id in that motion event.\n     * </p><p>\n     * Mouse and stylus buttons can be retrieved using {@link #getButtonState()}.

components. A View\n     * occupies a rectangular area on the screen and is responsible for drawing and\n     * event handling. View is the base class for <em>widgets</em>, which are\n     * used to create interactive UI components (buttons, text fields, etc.). The\n     * {@link android.view.ViewGroup} subclass is the base class for <em>layouts</em>, which\n     * are invisible containers that hold other Views (or other ViewGroups) and define\n     * their layout properties.\n     * </p>\n     *\n     * <div class=\"special reference\">\n     * <h3>Developer Guides</h3>\n     * <p>For information about using this class to develop your application's user interface,\n     * read the <a href=\"{@docRoot}guide/topics/ui/index.html\">User Interface</a> developer guide.\n     * </div>\n     *\n     * <a name=\"Using\"></a>\n     * <h3>Using Views</h3>\n     * <p>\n     * All of the views in a window are arranged in a single tree. You can add views\n     * either from code or by specifying a tree of views in one or more XML layout\n     * files. There are many specialized subclasses of views that act as controls or\n     * are capable of displaying text, images, or other content.\n     * </p>\n     * <p>\n     * Once you have created a tree of views, there are typically a few types of\n     * common operations you may wish to perform:\n     * <ul>\n     * <li><strong>Set properties:</strong> for example setting the text of a\n     * {@link android.widget.TextView}. The available properties and the methods\n     * that set them will vary among the different subclasses of views. Note that\n     * properties that are known at build time can be set in the XML layout\n     * files.</li>\n     * <li><strong>Set focus:</strong> The framework will handled moving focus in\n     * response to user input. To force focus to a specific view, call\n     * {@link #requestFocus}.</li>\n     * <li><strong>Set up listeners:</strong> Views allow clients to set listeners\n     * that will be notified when something interesting happens to the view. For\n     * example, all views will let you set a listener to be notified when the view\n     * gains or loses focus. You can register such a listener using\n     * {@link #setOnFocusChangeListener(android.view.View.OnFocusChangeListener)}.\n     * Other view subclasses offer more specialized listeners. For example, a Button\n     * exposes a listener to notify clients when the button is clicked.</li>\n     * <li><strong>Set visibility:</strong> You can hide or show views using\n     * {@link #setVisibility(int)}.</li>\n     * </ul>\n     * </p>\n     * <p><em>\n     * Note: The Android framework is responsible for measuring, laying out and\n     * drawing views. You should not call methods that perform these actions on\n     * views yourself unless you are actually implementing a\n     * {@link android.view.ViewGroup}.\n     * </em></p>\n     *\n     * <a name=\"Lifecycle\"></a>\n     * <h3>Implementing a Custom View</h3>\n     *\n     * <p>\n     * To implement a custom view, you will usually begin by providing overrides for\n     * some of the standard methods that the framework calls on all views.

A view has a location,\n     * expressed as a pair of <em>left</em> and <em>top</em> coordinates, and\n     * two dimensions, expressed as a width and a height. The unit for location\n     * and dimensions is the pixel.\n     * </p>\n     *\n     * <p>\n     * It is possible to retrieve the location of a view by invoking the methods\n     * {@link #getLeft()} and {@link #getTop()}. The former returns the left, or X,\n     * coordinate of the rectangle representing the view. The latter returns the\n     * top, or Y, coordinate of the rectangle representing the view. These methods\n     * both return the location of the view relative to its parent. For instance,\n     * when getLeft() returns 20, that means the view is located 20 pixels to the\n     * right of the left edge of its direct parent.\n     * </p>\n     *\n     * <p>\n     * In addition, several convenience methods are offered to avoid unnecessary\n     * computations, namely {@link #getRight()} and {@link #getBottom()}.\n     * These methods return the coordinates of the right and bottom edges of the\n     * rectangle representing the view. For instance, calling {@link #getRight()}\n     * is similar to the following computation: <code>getLeft() + getWidth()</code>\n     * (see <a href=\"#SizePaddingMargins\">Size</a> for more information about the width.)\n     * </p>\n     *\n     * <a name=\"SizePaddingMargins\"></a>\n     * <h3>Size, padding and margins</h3>\n     * <p>\n     * The size of a view is expressed with a width and a height. A view actually\n     * possess two pairs of width and height values.\n     * </p>\n     *\n     * <p>\n     * The first pair is known as <em>measured width</em> and\n     * <em>measured height</em>. These dimensions define how big a view wants to be\n     * within its parent (see <a href=\"#Layout\">Layout</a> for more details.) The\n     * measured dimensions can be obtained by calling {@link #getMeasuredWidth()}\n     * and {@link #getMeasuredHeight()}.\n     * </p>\n     *\n     * <p>\n     * The second pair is simply known as <em>width</em> and <em>height</em>, or\n     * sometimes <em>drawing width</em> and <em>drawing height</em>. These\n     * dimensions define the actual size of the view on screen, at drawing time and\n     * after layout. These values may, but do not have to, be different from the\n     * measured width and height. The width and height can be obtained by calling\n     * {@link #getWidth()} and {@link #getHeight()}.\n     * </p>\n     *\n     * <p>\n     * To measure its dimensions, a view takes into account its padding. The padding\n     * is expressed in pixels for the left, top, right and bottom parts of the view.\n     * Padding can be used to offset the content of the view by a specific amount of\n     * pixels. For instance, a left padding of 2 will push the view's content by\n     * 2 pixels to the right of the left edge. Padding can be set using the\n     * {@link #setPadding(int, int, int, int)} or {@link #setPaddingRelative(int, int, int, int)}\n     * method and queried by calling {@link #getPaddingLeft()}, {@link #getPaddingTop()},\n     * {@link #getPaddingRight()}, {@link #getPaddingBottom()}, {@link #getPaddingStart()},\n     * {@link #getPaddingEnd()}.\n     * </p>\n     *\n     * <p>\n     * Even though a view can define a padding, it does not provide any support for\n     * margins. However, view groups provide such a support. Refer to\n     * {@link android.view.ViewGroup} and\n     * {@link android.view.ViewGroup.MarginLayoutParams} for further information.\n     * </p>\n     *\n     * <a name=\"Layout\"></a>\n     * <h3>Layout</h3>\n     * <p>\n     * Layout is a two pass process: a measure pass and a layout pass. The measuring\n     * pass is implemented in {@link #measure(int, int)} and is a top-down traversal\n     * of the view tree. Each view pushes dimension specifications down the tree\n     * during the recursion. At the end of the measure pass, every view has stored\n     * its measurements. The second pass happens in\n     * {@link #layout(int,int,int,int)} and is also top-down. During\n     * this pass each parent is responsible for positioning all of its children\n     * using the sizes computed in the measure pass.\n     * </p>\n     *\n     * <p>\n     * When a view's measure() method returns, its {@link #getMeasuredWidth()} and\n     * {@link #getMeasuredHeight()} values must be set, along with those for all of\n     * that view's descendants. A view's measured width and measured height values\n     * must respect the constraints imposed by the view's parents. This guarantees\n     * that at the end of the measure pass, all parents accept all of their\n     * children's measurements. A parent view may call measure() more than once on\n     * its children. For example, the parent may measure each child once with\n     * unspecified dimensions to find out how big they want to be, then call\n     * measure() on them again with actual numbers if the sum of all the children's\n     * unconstrained sizes is too big or too small.\n     * </p>\n     *\n     * <p>\n     * The measure pass uses two classes to communicate dimensions. The\n     * {@link MeasureSpec} class is used by views to tell their parents how they\n     * want to be measured and positioned. The base LayoutParams class just\n     * describes how big the view wants to be for both width and height. For each\n     * dimension, it can specify one of:\n     * <ul>\n     * <li> an exact number\n     * <li>MATCH_PARENT, which means the view wants to be as big as its parent\n     * (minus padding)\n     * <li> WRAP_CONTENT, which means that the view wants to be just big enough to\n     * enclose its content (plus padding).\n     * </ul>\n     * There are subclasses of LayoutParams for different subclasses of ViewGroup.\n     * For example, AbsoluteLayout has its own subclass of LayoutParams which adds\n     * an X and Y value.\n     * </p>\n     *\n     * <p>\n     * MeasureSpecs are used to push requirements down the tree from parent to\n     * child. A MeasureSpec can be in one of three modes:\n     * <ul>\n     * <li>UNSPECIFIED: This is used by a parent to determine the desired dimension\n     * of a child view. For example, a LinearLayout may call measure() on its child\n     * with the height set to UNSPECIFIED and a width of EXACTLY 240 to find out how\n     * tall the child view wants to be given a width of 240 pixels.\n     * <li>EXACTLY: This is used by the parent to impose an exact size on the\n     * child. The child must use this size, and guarantee that all of its\n     * descendants will fit within this size.\n     * <li>AT_MOST: This is used by the parent to impose a maximum size on the\n     * child. The child must gurantee that it and all of its descendants will fit\n     * within this size.\n     * </ul>\n     * </p>\n     *\n     * <p>\n     * To intiate a layout, call {@link #requestLayout}. This method is typically\n     * called by a view on itself when it believes that is can no longer fit within\n     * its current bounds.\n     * </p>\n     *\n     * <a name=\"Drawing\"></a>\n     * <h3>Drawing</h3>\n     * <p>\n     * Drawing is handled by walking the tree and rendering each view that\n     * intersects the invalid region.

The view\n     * handles the event and notifies any listeners.</li>\n     * <li>If in the course of processing the event, the view's bounds may need\n     * to be changed, the view will call {@link #requestLayout()}.</li>\n     * <li>Similarly, if in the course of processing the event the view's appearance\n     * may need to be changed, the view will call {@link #invalidate()}.</li>\n     * <li>If either {@link #requestLayout()} or {@link #invalidate()} were called,\n     * the framework will take care of measuring, laying out, and drawing the tree\n     * as appropriate.</li>\n     * </ol>\n     * </p>\n     *\n     * <p><em>Note: The entire view tree is single threaded.

Views indicate their willingness to take focus\n     * through the {@link #isFocusable} method. To change whether a view can take\n     * focus, call {@link #setFocusable(boolean)}.  When in touch mode (see notes below)\n     * views indicate whether they still would like focus via {@link #isFocusableInTouchMode}\n     * and can change this via {@link #setFocusableInTouchMode(boolean)}.\n     * </p>\n     * <p>\n     * Focus movement is based on an algorithm which finds the nearest neighbor in a\n     * given direction. In rare cases, the default algorithm may not match the\n     * intended behavior of the developer. In these situations, you can provide\n     * explicit overrides by using these XML attributes in the layout file:\n     * <pre>\n     * nextFocusDown\n     * nextFocusLeft\n     * nextFocusRight\n     * nextFocusUp\n     * </pre>\n     * </p>\n     *\n     *\n     * <p>\n     * To get a particular view to take focus, call {@link #requestFocus()}.\n     * </p>\n     *\n     * <a name=\"TouchMode\"></a>\n     * <h3>Touch Mode</h3>\n     * <p>\n     * When a user is navigating a user interface via directional keys such as a D-pad, it is\n     * necessary to give focus to actionable items such as buttons so the user can see\n     * what will take input.  If the device has touch capabilities, however, and the user\n     * begins interacting with the interface by touching it, it is no longer necessary to\n     * always highlight, or give focus to, a particular view.  This motivates a mode\n     * for interaction named 'touch mode'.\n     * </p>\n     * <p>\n     * For a touch capable device, once the user touches the screen, the device\n     * will enter touch mode.  From this point onward, only views for which\n     * {@link #isFocusableInTouchMode} is true will be focusable, such as text editing widgets.\n     * Other views that are touchable, like buttons, will not take focus when touched; they will\n     * only fire the on click listeners.\n     * </p>\n     * <p>\n     * Any time a user hits a directional key, such as a D-pad direction, the view device will\n     * exit touch mode, and find a view to take focus, so that the user may resume interacting\n     * with the user interface without touching the screen again.\n     * </p>\n     * <p>\n     * The touch mode state is maintained across {@link android.app.Activity}s.

These properties are\n     * available both in the {@link Property} form as well as in similarly-named setter/getter\n     * methods (such as {@link #setAlpha(float)} for {@link #ALPHA}).

These {@link android.animation.Animator Animator}-based\n     * classes change actual properties of the View object, such as {@link #setAlpha(float) alpha} and\n     * {@link #setTranslationX(float) translationX}. This behavior is contrasted to that of the pre-3.0\n     * {@link android.view.animation.Animation Animation}-based classes, which instead animate only\n     * how the view is drawn on the display. In particular, the {@link ViewPropertyAnimator} class\n     * makes animating these View properties particularly easy and efficient.\n     * </p>\n     * <p>\n     * Alternatively, you can use the pre-3.0 animation classes to animate how Views are rendered.\n     * You can attach an {@link Animation} object to a view using\n     * {@link #setAnimation(Animation)} or\n     * {@link #startAnimation(Animation)}. The animation can alter the scale,\n     * rotation, translation and alpha of a view over time. If the animation is\n     * attached to a view that has children, the animation will affect the entire\n     * subtree rooted by that node.

Views that are {@link android.view.View#GONE} are\n     * used for sizing\n     * only if {@link #setMeasureAllChildren(boolean) setConsiderGoneChildrenWhenMeasuring()}\n     * is set to true.\n     *\n     * @attr ref android.R.styleable#FrameLayout_foreground\n     * @attr ref android.R.styleable#FrameLayout_foregroundGravity\n     * @attr ref android.R.styleable#FrameLayout_measureAllChildren\n     */\n    export class FrameLayout extends ViewGroup {\n        static DEFAULT_CHILD_GRAVITY = Gravity.TOP | Gravity.LEFT;\n\n        mMeasureAllChildren = false;\n        mForeground:Drawable;\n        private mForegroundPaddingLeft = 0;\n        private mForegroundPaddingTop = 0;\n        private mForegroundPaddingRight = 0;\n        private mForegroundPaddingBottom = 0;\n        private mSelfBounds = new Rect();\n        private mOverlayBounds = new Rect();\n        private mForegroundGravity = Gravity.FILL;\n        mForegroundInPadding = true;\n        mForegroundBoundsChanged = false;\n        private mMatchParentChildren = new Array<View>(1);\n\n        constructor(context:android.content.Context, bindElement?:HTMLElement, defStyle?:Map<string, string>) {\n            super(context, bindElement, defStyle);\n\n            const a = context.obtainStyledAttributes(bindElement, defStyle);\n            this.mForegroundGravity = Gravity.parseGravity(a.getAttrValue('foregroundGravity'), this.mForegroundGravity);\n\n            const d = a.getDrawable('foreground');\n            if (d != null) {\n                this.setForeground(d);\n            }\n\n            if (a.getBoolean('measureAllChildren', false)) {\n                this.setMeasureAllChildren(true);\n            }\n\n            this.mForegroundInPadding = a.getBoolean('foregroundInsidePadding', true);\n            a.recycle();\n        }\n\n        protected createClassAttrBinder(): androidui.attr.AttrBinder.ClassBinderMap {\n            return super.createClassAttrBinder().set('foregroundGravity', {\n                setter(v:FrameLayout, value:any, attrBinder:AttrBinder) {\n                    v.mForegroundGravity = attrBinder.parseGravity(value, v.mForegroundGravity);\n                }, getter(v:FrameLayout) {\n                    return v.mForegroundGravity;\n                }\n            }).set('foreground', {\n                setter(v:FrameLayout, value:any, attrBinder:AttrBinder) {\n                    v.setForeground(attrBinder.parseDrawable(value));\n                }, getter(v:FrameLayout) {\n                    return v.getForeground();\n                }\n            }).set('measureAllChildren', {\n                setter(v:FrameLayout, value:any, attrBinder:AttrBinder) {\n                    if (attrBinder.parseBoolean(value)) {\n                        v.setMeasureAllChildren(true);\n                    }\n                }, getter(v:FrameLayout) {\n                    return v.mMeasureAllChildren;\n                }\n            });\n        }\n\n        /**\n         * Describes how the foreground is positioned.\n         *\n         * @return foreground gravity.\n         *\n         * @see #setForegroundGravity(int)\n         *\n         * @attr ref android.R.styleable#FrameLayout_foregroundGravity\n         */\n        getForegroundGravity():number {\n            return this.mForegroundGravity;\n        }\n\n        /**\n         * Describes how the foreground is positioned.

An easy way to\n     * do this is with an XML drawable \"selector.\" For example:</p>\n     * <pre>\n     * &lt;?xml version=\"1.0\" encoding=\"utf-8\"?&gt;\n     * &lt;selector xmlns:android=\"http://schemas.android.com/apk/res/android\"&gt;\n     *     &lt;item android:state_pressed=\"true\"\n     *           android:drawable=\"@drawable/button_pressed\" /&gt; &lt;!-- pressed --&gt;\n     *     &lt;item android:state_focused=\"true\"\n     *           android:drawable=\"@drawable/button_focused\" /&gt; &lt;!-- focused --&gt;\n     *     &lt;item android:drawable=\"@drawable/button_normal\" /&gt; &lt;!-- default --&gt;\n     * &lt;/selector&gt;</pre>\n     *\n     * <p>Save the XML file in your project {@code res/drawable/} folder and then\n     * reference it as a drawable for the source of your ImageButton (in the\n     * {@code android:src} attribute). Android will automatically change the image\n     * based on the state of the button and the corresponding images\n     * defined in the XML.</p>\n     *\n     * <p>The order of the {@code <item>} elements is important because they are\n     * evaluated in order. This is why the \"normal\" button image comes last, because\n     * it will only be applied after {@code android:state_pressed} and {@code\n     * android:state_focused} have both evaluated false.</p>\n     *\n     * <p>See the <a href=\"{@docRoot}guide/topics/ui/controls/button.html\">Buttons</a>\n     * guide.</p>\n     *\n     * <p><strong>XML attributes</strong></p>\n     * <p>\n     * See {@link android.R.styleable#ImageView Button Attributes},\n     * {@link android.R.styleable#View View Attributes}\n     * </p>\n     */\n    export class ImageButton extends ImageView {\n        constructor(context:android.content.Context, bindElement?:HTMLElement, defStyle = android.R.attr.imageButtonStyle){\n            super(context, bindElement, defStyle);\n        }\n    }\n}"

Displays a bar to the user\n * representing how far the operation has progressed; the application can \n * change the amount of progress (modifying the length of the bar) as it moves \n * forward.  There is also a secondary progress displayable on a progress bar\n * which is useful for displaying intermediate progress, such as the buffer\n * level during a streaming playback progress bar.\n * </p>\n *\n * <p>\n * A progress bar can also be made indeterminate. In indeterminate mode, the\n * progress bar shows a cyclic animation without an indication of progress. This mode is used by\n * applications when the length of the task is unknown. The indeterminate progress bar can be either\n * a spinning wheel or a horizontal bar.\n * </p>\n *\n * <p>The following code example shows how a progress bar can be used from\n * a worker thread to update the user interface to notify the user of progress:\n * </p>\n * \n * <pre>\n * public class MyActivity extends Activity {\n *     private static final int PROGRESS = 0x1;\n *\n *     private ProgressBar mProgress;\n *     private int mProgressStatus = 0;\n *\n *     private Handler mHandler = new Handler();\n *\n *     protected void onCreate(Bundle icicle) {\n *         super.onCreate(icicle);\n *\n *         setContentView(R.layout.progressbar_activity);\n *\n *         mProgress = (ProgressBar) findViewById('progress'_bar);\n *\n *         // Start lengthy operation in a background thread\n *         new Thread(new Runnable() {\n *             public void run() {\n *                 while (mProgressStatus &lt; 100) {\n *                     mProgressStatus = doWork();\n *\n *                     // Update the progress bar\n *                     mHandler.post(new Runnable() {\n *                         public void run() {\n *                             mProgress.setProgress(mProgressStatus);\n *                         }\n *                     });\n *                 }\n *             }\n *         }).start();\n *     }\n * }</pre>\n *\n * <p>To add a progress bar to a layout file, you can use the {@code &lt;ProgressBar&gt;} element.\n * By default, the progress bar is a spinning wheel (an indeterminate indicator). To change to a\n * horizontal progress bar, apply the {@link android.R.style#Widget_ProgressBar_Horizontal\n * Widget.ProgressBar.Horizontal} style, like so:</p>\n *\n * <pre>\n * &lt;ProgressBar\n *     style=\"@android:style/Widget.ProgressBar.Horizontal\"\n *     ... /&gt;</pre>\n *\n * <p>If you will use the progress bar to show real progress, you must use the horizontal bar. You\n * can then increment the  progress with {@link #incrementProgressBy incrementProgressBy()} or\n * {@link #setProgress setProgress()}. By default, the progress bar is full when it reaches 100. If\n * necessary, you can adjust the maximum value (the value for a full bar) using the {@link\n * android.R.styleable#ProgressBar_max android:max} attribute. Other attributes available are listed\n * below.</p>\n *\n * <p>Another common style to apply to the progress bar is {@link\n * android.R.style#Widget_ProgressBar_Small Widget.ProgressBar.Small}, which shows a smaller\n * version of the spinning wheel&mdash;useful when waiting for content to load.\n * For example, you can insert this kind of progress bar into your default layout for\n * a view that will be populated by some content fetched from the Internet&mdash;the spinning wheel\n * appears immediately and when your application receives the content, it replaces the progress bar\n * with the loaded content. For example:</p>\n *\n * <pre>\n * &lt;LinearLayout\n *     android:orientation=\"horizontal\"\n *     ... &gt;\n *     &lt;ProgressBar\n *         android:layout_width=\"wrap_content\"\n *         android:layout_height=\"wrap_content\"\n *         style=\"@android:style/Widget.ProgressBar.Small\"\n *         android:layout_marginRight=\"5dp\" /&gt;\n *     &lt;TextView\n *         android:layout_width=\"wrap_content\"\n *         android:layout_height=\"wrap_content\"\n *         android:text=\"@string/loading\" /&gt;\n * &lt;/LinearLayout&gt;</pre>\n *\n * <p>Other progress bar styles provided by the system include:</p>\n * <ul>\n * <li>{@link android.R.style#Widget_ProgressBar_Horizontal Widget.ProgressBar.Horizontal}</li>\n * <li>{@link android.R.style#Widget_ProgressBar_Small Widget.ProgressBar.Small}</li>\n * <li>{@link android.R.style#Widget_ProgressBar_Large Widget.ProgressBar.Large}</li>\n * <li>{@link android.R.style#Widget_ProgressBar_Inverse Widget.ProgressBar.Inverse}</li>\n * <li>{@link android.R.style#Widget_ProgressBar_Small_Inverse\n * Widget.ProgressBar.Small.Inverse}</li>\n * <li>{@link android.R.style#Widget_ProgressBar_Large_Inverse\n * Widget.ProgressBar.Large.Inverse}</li>\n * </ul>\n * <p>The \"inverse\" styles provide an inverse color scheme for the spinner, which may be necessary\n * if your application uses a light colored theme (a white background).</p>\n *  \n * <p><strong>XML attributes</b></strong> \n * <p> \n * See {@link android.R.styleable#ProgressBar
