返回与键值对应的数据，若键值的上游不存在，会返回undefined或null\n\ndemo\n\n\tData.get('a');//undefined\n\tData.get('a.b.c')//undefined\n\n**注：**此处获取的是Data中数据的深拷贝，即get接口返回的数据是Data中对应数据的一份深拷贝。之所以牺牲性能，这样设计是因为深拷贝能避免很多难以预知的bug。\n\n下面是深拷贝，浅拷贝和引用的区别：\n\t\n\t//深拷贝\n\tvar a = Data.get('a');//若a为{b:{c:1}}\n\ta.b.c= 2;//此处更改不会影像Data中的数据\n\tData.get('a.b.c')//此处输出1\n\n\t//浅拷贝\n\tvar a = Data.get('a');//若a为{b:{c:1}}\n\ta.b.c=

{String} 放入Data中数据的键值\n- val {val} [可选] 放入Data中的数据\n- return {Bollean} 是否添加成功\n\n传入key + val 和 传入 {key: val}的方式等价，可以选择自己喜欢的方式，键值的方式更清晰，作者推荐前一种，记住只使用同一种方式会让事情变得简单。\n\ndemo\n\t\n\t//传入值类型\n\tD.set('a', 1);\n\tD.get('a');//1\n\n\t//传入引用类型\n\tD.set('a', {b: 1});\n\tD.get('a.b');//1\n\n\tD.set('a.b.c', 1);\n\tD.set('a', {b: {c: 1}}});//这两种功能一样\n\n###key\nkey值是Data的基石，key是一个字符串，Data的key支持任何utf-8编码的字符，js支持的就可以\n\n- 字母 abc\n- 数字 123\n- 特殊字符 _-+$;'\"...\n- 甚至是汉字 颜海镜\n\nData都可以完美支持，同时key还有类似对象属性的特性，a.b.c是获取a下的b下的c，其中.号是分隔符，可以想像成js中的对象（其实Data内部确实是按对象处理）。\n\n\tD.set('a', {});\n\tD.set('a.b', 1);\n\tD.set('a.c', [1]);\n\tD.set('a.1.1', 1);//此处会创建数组\n\t\n`D.get('a')`的输出如下：\n\n\t{\n\t\t1: [1],\n\t\tb:1,\n\t\tc:[undefined ,1]\n\t}\n\t\nData可以将传入的键，智能转换为对应的空间，支持对象和数组。\n\n##sub*\nsub方法是Data的核心方法，用来订阅消息，订阅指定键值的指定事件，在对应的值发生变化时，会得到通知（当传入对象和数组时，消息会下发到其子元素）。\n\n- type {String} 订阅消息的类型 （可选值：set, add, update, delete 分别代表 设置，添加，更新，删除，其中set是通用类型，其他三个为细分类型，并且互斥）\n- key {String} 订阅消息的键值\n- callback {Function} 消息接受函数\n- return {Number} 消息的同意id用于取消订阅事件用\n\ndemo\n\t\n\tD.sub('set', 'a', function (e) {console.log(e)});\n\t\n\tD.set('a', 1);//a值更新，会调用回调函数\n\n###e\n\n- type {String} 消息的类型\n- key {String} 消息的建\n- data {val} 设置的值\n\n##unsub\n\n取消订阅的消息。\n\n- type {String} 取消订阅消息的类型 （可选值：set, add, update, delete 分别代表 设置，添加，更新，删除，其中set是通用类型，其他三个为细分类型，并且互斥）\n- key {String} 取消订阅消息的键值\n- id {Number} [可选] sub是返回的消息的id\n- return {Bollean} 是否取消成功\n\n若id为空则会删除所有对应键值和类型的所有事件。\n\ndemo\n\n\tvar id = D.sub('set', 'a', function (e) {console.log(e)});\n\t\n\tD.set('a', 1);//a值更新，会调用回调函数\n\t\n\tD.unsub('set', 'a', id);\n\t\n\tD.set('a', 1);//不会在收到通知\n\n##注意事项\n\n由于Data设计之初希望支持跨平台，所以要支持ecmascript类型数据，Data希望放入的是数据，期望的是原生数据，支持 Number，Bollean，String，Object，null，undefined，Array。对于Object和Array会是其深拷贝值，并且会创造层级。\n\n对于其他类型对象js都默认为值类型，如dom节点，仅简单赋值其引用，所以消息无法下发到dom的子元素上，但get接口可以取到其子元素。其他类型对象还包括：\n\n- window\n- document\n- dom\n- dom list\n- node list\n\n请不要将复杂对象和引用自身的对象放入Data中，会造成性能的严重下降，和不可预知的问题。复杂对象包括如下：\n\n- jquery对象\n\n建议放入原生数据，对于jquery对象可传入其查询字符串。" }, { "path": "gulpfile.js", "content": "/**\n * @file gulp file\n * @author

Sometimes it's called a \"filter\",\n// but that's not a great name for it, since that implies a thing where\n// some bits pass through, and others are simply ignored. (That would\n// be a valid example of a transform, of course.)\n//\n// While the output is causally related to the input, it's not a\n// necessarily symmetric or synchronous transformation. For example,\n// a zlib stream might take multiple plain-text writes(), and then\n// emit a single compressed chunk some time in the future.\n//\n// Here's how this works:\n//\n// The Transform stream has all the aspects of the readable and writable\n// stream classes. When you write(chunk), that calls _write(chunk,cb)\n// internally, and returns false if there's a lot of pending writes\n// buffered up. When you call read(), that calls _read(n) until\n// there's enough pending readable data buffered up.\n//\n// In a transform stream, the written data is placed in a buffer. When\n// _read(n) is called, it transforms the queued up data, calling the\n// buffered _write cb's as it consumes chunks. If consuming a single\n// written chunk would result in multiple output chunks, then the first\n// outputted bit calls the readcb, and subsequent chunks just go into\n// the read buffer, and will cause it to emit 'readable' if necessary.\n//\n// This way, back-pressure is actually determined by the reading side,\n// since _read has to be called to start processing a new chunk. However,\n// a pathological inflate type of transform can cause excessive buffering\n// here. For example, imagine a stream where every byte of input is\n// interpreted as an integer from 0-255, and then results in that many\n// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in\n// 1kb of data being output. In this case, you could write a very small\n// amount of input, and end up with a very large amount of output. In\n// such a pathological inflating mechanism, there'd be no way to tell\n// the system to stop doing the transform.
