The value of this property should be a string representing a path + to another object or a custom binding instance created using Binding helpers + (see "One Way Bindings"): + + ``` + valueBinding: "MyApp.someController.title" + ``` + + This will create a binding from `MyApp.someController.title` to the `value` + property of your object instance automatically. Now the two values will be + kept in sync. + + ## One Way Bindings + + One especially useful binding customization you can use is the `oneWay()` + helper. This helper tells Ember that you are only interested in + receiving changes on the object you are binding from. For example, if you + are binding to a preference and you want to be notified if the preference + has changed, but your object will not be changing the preference itself, you + could do: + + ``` + bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles") + ``` + + This way if the value of `MyApp.preferencesController.bigTitles` changes the + `bigTitles` property of your object will change also. However, if you + change the value of your `bigTitles` property, it will not update the + `preferencesController`. + + One way bindings are almost twice as fast to setup and twice as fast to + execute because the binding only has to worry about changes to one side. + + You should consider using one way bindings anytime you have an object that + may be created frequently and you do not intend to change a property; only + to monitor it for changes (such as in the example above). + + ## Adding Bindings Manually + + All of the examples above show you how to configure a custom binding, but the + result of these customizations will be a binding template, not a fully active + Binding instance. The binding will actually become active only when you + instantiate the object the binding belongs to. It is useful however, to + understand what actually happens when the binding is activated. + + For a binding to function it must have at least a `from` property and a `to` + property. The `from` property path points to the object/key that you want to + bind from while the `to` path points to the object/key you want to bind to. + + When you define a custom binding, you are usually describing the property + you want to bind from (such as `MyApp.someController.value` in the examples + above). When your object is created, it will automatically assign the value + you want to bind `to` based on the name of your binding key. In the + examples above, during init, Ember objects will effectively call + something like this on your binding: + + ```javascript + binding = Ember.Binding.from("valueBinding").to("value"); + ``` + + This creates a new binding instance based on the template you provide, and + sets the to path to the `value` property of the new object. Now that the + binding is fully configured with a `from` and a `to`, it simply needs to be + connected to become active. This is done through the `connect()` method: + + ```javascript + binding.connect(this); + ``` + + Note that when you connect a binding you pass the object you want it to be + connected to. This object will be used as the root for both the from and + to side of the binding when inspecting relative paths. This allows the + binding to be automatically inherited by subclassed objects as well. + + This also allows you to bind between objects using the paths you declare in + `from` and `to`: + + ```javascript + // Example 1 + binding = Ember.Binding.from("App.someObject.value").to("value"); + binding.connect(this); + + // Example 2 + binding = Ember.Binding.from("parentView.value").to("App.someObject.value"); + binding.connect(this); + ``` + + Now that the binding is connected, it will observe both the from and to side + and relay changes. + + If you ever needed to do so (you almost never will, but it is useful to + understand this anyway), you could manually create an active binding by + using the `Ember.bind()` helper method. (This is the same method used by + to setup your bindings on objects): + + ```javascript + Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value"); + ``` + + Both of these code fragments have the same effect as doing the most friendly + form of binding creation like so: + + ```javascript + MyApp.anotherObject = Ember.Object.create({ + valueBinding: "MyApp.someController.value", + + // OTHER CODE FOR THIS OBJECT... + }); + ``` + + Ember's built in binding creation method makes it easy to automatically + create bindings for you.

What an opportunity to - // optimize this code!" then to you I say: stop! For I have a tale to tell. - // - // First, this code must be compatible with simple-dom for rendering on the - // server where there is no real DOM.

Then, we could just implement our own `item` - // method in simple-dom and walk the child node linked list there, allowing - // us to retain the performance advantages of the (surely optimized) `item()` - // API in the browser. - // - // Unfortunately, an enterprising soul named Samy Alzahrani discovered that in - // IE8, accessing an item out-of-bounds via `item()` causes an exception where - // other browsers return null. This necessitated a... check of - // `childNodes.length`, bringing us back around to having to support a - // full-fidelity `childNodes` array! - // - // Worst of all, Kris Selden investigated how browsers are actualy implemented - // and discovered that they're all linked lists under the hood anyway. Accessing - // `childNodes` requires them to allocate a new live collection backed by that - // linked list, which is itself a rather expensive operation. Our assumed - // optimization had backfired!

If a template is not later provided for the view instance - the `defaultTemplate` value will be used: - - ```javascript - AView = Ember.View.extend({ - defaultTemplate: Ember.Handlebars.compile('I was the default'), - template: null, - templateName: null - }); - ``` - - Will result in instances with an HTML representation of: - - ```html - I was the default - ``` - - If a `template` or `templateName` is provided it will take precedence over - `defaultTemplate`: - - ```javascript - AView = Ember.View.extend({ - defaultTemplate: Ember.Handlebars.compile('I was the default') - }); - - aView = AView.create({ - template: Ember.Handlebars.compile('I was the template, not default') - }); - ``` - - Will result in the following HTML representation when rendered: - - ```html - I was the template, not default - ``` - - ## View Context - - The default context of the compiled template is the view's controller: - - ```javascript - AView = Ember.View.extend({ - template: Ember.Handlebars.compile('Hello {{excitedGreeting}}') - }); - - aController = Ember.Object.create({ - firstName: 'Barry', - excitedGreeting: function() { - return this.get("content.firstName") + "!!!" - }.property() - }); - - aView = AView.create({ - controller: aController - }); - ``` - - Will result in an HTML representation of: - - ```html - Hello Barry!!! - ``` - - A context can also be explicitly supplied through the view's `context` - property. If the view has neither `context` nor `controller` properties, the - `parentView`'s context will be used. - - ## Layouts - - Views can have a secondary template that wraps their main template. Like - primary templates, layouts can be any function that accepts an optional - context parameter and returns a string of HTML that will be inserted inside - view's tag. Views whose HTML element is self closing (e.g. ``) - cannot have a layout and this property will be ignored. - - Most typically in Ember a layout will be a compiled `Ember.Handlebars` - template. - - A view's layout can be set directly with the `layout` property or reference - an existing Handlebars template by name with the `layoutName` property. - - A template used as a layout must contain a single use of the Handlebars - `{{yield}}` helper. The HTML contents of a view's rendered `template` will be - inserted at this location: - - ```javascript - AViewWithLayout = Ember.View.extend({ - layout: Ember.Handlebars.compile("{{yield}}"), - template: Ember.Handlebars.compile("I got wrapped") - }); - ``` - - Will result in view instances with an HTML representation of: - - ```html - - - I got wrapped - - - ``` - - See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield) - for more information. - - ## Responding to Browser Events - - Views can respond to user-initiated events in one of three ways: method - implementation, through an event manager, and through `{{action}}` helper use - in their template or layout. - - ### Method Implementation - - Views can respond to user-initiated events by implementing a method that - matches the event name. A `jQuery.Event` object will be passed as the - argument to this method. - - ```javascript - AView = Ember.View.extend({ - click: function(event) { - // will be called when when an instance's - // rendered element is clicked - } - }); - ``` - - ### Event Managers - - Views can define an object as their `eventManager` property. This object can - then implement methods that match the desired event names. Matching events - that occur on the view's rendered HTML or the rendered HTML of any of its DOM - descendants will trigger this method. A `jQuery.Event` object will be passed - as the first argument to the method and an `Ember.View` object as the - second. The `Ember.View` will be the view whose rendered HTML was interacted - with. This may be the view with the `eventManager` property or one of its - descendant views. - - ```javascript - AView = Ember.View.extend({ - eventManager: Ember.Object.create({ - doubleClick: function(event, view) { - // will be called when when an instance's - // rendered element or any rendering - // of this view's descendant - // elements is clicked - } - }) - }); - ``` - - An event defined for an event manager takes precedence over events of the - same name handled through methods on the view. - - ```javascript - AView = Ember.View.extend({ - mouseEnter: function(event) { - // will never trigger. - }, - eventManager: Ember.Object.create({ - mouseEnter: function(event, view) { - // takes precedence over AView#mouseEnter - } - }) - }); - ``` - - Similarly a view's event manager will take precedence for events of any views - rendered as a descendant. A method name that matches an event name will not - be called if the view instance was rendered inside the HTML representation of - a view that has an `eventManager` property defined that handles events of the - name. Events not handled by the event manager will still trigger method calls - on the descendant. - - ```javascript - var App = Ember.Application.create(); - App.OuterView = Ember.View.extend({ - template: Ember.Handlebars.compile("outer {{#view 'inner'}}inner{{/view}} outer"), - eventManager: Ember.Object.create({ - mouseEnter: function(event, view) { - // view might be instance of either - // OuterView or InnerView depending on - // where on the page the user interaction occurred - } - }) - }); - - App.InnerView = Ember.View.extend({ - click: function(event) { - // will be called if rendered inside - // an OuterView because OuterView's - // eventManager doesn't handle click events - }, - mouseEnter: function(event) { - // will never be called if rendered inside - // an OuterView. - } - }); - ``` - - ### Handlebars `{{action}}` Helper - - See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action). - - ### Event Names - - All of the event handling approaches described above respond to the same set - of events. The names of the built-in events are listed below. (The hash of - built-in events exists in `Ember.EventDispatcher`.) Additional, custom events - can be registered by using `Ember.Application.customEvents`. - - Touch events: - - * `touchStart` - * `touchMove` - * `touchEnd` - * `touchCancel` - - Keyboard events - - * `keyDown` - * `keyUp` - * `keyPress` - - Mouse events - - * `mouseDown` - * `mouseUp` - * `contextMenu` - * `click` - * `doubleClick` - * `mouseMove` - * `focusIn` - * `focusOut` - * `mouseEnter` - * `mouseLeave` - - Form events: - - * `submit` - * `change` - * `focusIn` - * `focusOut` - * `input` - - HTML5 drag and drop events: - - * `dragStart` - * `drag` - * `dragEnter` - * `dragLeave` - * `dragOver` - * `dragEnd` - * `drop` - - ## Handlebars `{{view}}` Helper - - Other `Ember.View` instances can be included as part of a view's template by - using the `{{view}}` Handlebars helper.

You can use `denodeify` in Node.js or the - browser when you'd prefer to use promises over using callbacks. For example, - `denodeify` transforms the following: - - ```javascript - var fs = require('fs'); - - fs.readFile('myfile.txt', function(err, data){ - if (err) return handleError(err); - handleData(data); - }); - ``` - - into: - - ```javascript - var fs = require('fs'); - var readFile = RSVP.denodeify(fs.readFile); - - readFile('myfile.txt').then(handleData, handleError); - ``` - - If the node function has multiple success parameters, then `denodeify` - just returns the first one: - - ```javascript - var request = RSVP.denodeify(require('request')); - - request('http://example.com').then(function(res) { - // ... - }); - ``` - - However, if you need all success parameters, setting `denodeify`'s - second parameter to `true` causes it to return all success parameters - as an array: - - ```javascript - var request = RSVP.denodeify(require('request'), true); - - request('http://example.com').then(function(result) { - // result[0] -> res - // result[1] -> body - }); - ``` - - Or if you pass it an array with names it returns the parameters as a hash: - - ```javascript - var request = RSVP.denodeify(require('request'), ['res', 'body']); - - request('http://example.com').then(function(result) { - // result.res - // result.body - }); - ``` - - Sometimes you need to retain the `this`: - - ```javascript - var app = require('express')(); - var render = RSVP.denodeify(app.render.bind(app)); - ``` - - The denodified function inherits from the original function. It works in all - environments, except IE 10 and below. Consequently all properties of the original - function are available to you. However, any properties you change on the - denodeified function won't be changed on the original function. Example: - - ```javascript - var request = RSVP.denodeify(require('request')), - cookieJar = request.jar(); // <- Inheritance is used here - - request('http://example.com', {jar: cookieJar}).then(function(res) { - // cookieJar.cookies holds now the cookies returned by example.com - }); - ``` - - Using `denodeify` makes it easier to compose asynchronous operations instead - of using callbacks. For example, instead of: - - ```javascript - var fs = require('fs'); - - fs.readFile('myfile.txt', function(err, data){ - if (err) { ... } // Handle error - fs.writeFile('myfile2.txt', data, function(err){ - if (err) { ... } // Handle error - console.log('done') - }); - }); - ``` - - you can chain the operations together using `then` from the returned promise: - - ```javascript - var fs = require('fs'); - var readFile = RSVP.denodeify(fs.readFile); - var writeFile = RSVP.denodeify(fs.writeFile); - - readFile('myfile.txt').then(function(data){ - return writeFile('myfile2.txt', data); - }).then(function(){ - console.log('done') - }).catch(function(error){ - // Handle error - }); - ``` - - @method denodeify - @static - @for RSVP - @param {Function} nodeFunc a 'node-style' function that takes a callback as - its last argument. The callback expects an error to be passed as its first - argument (if an error occurred, otherwise null), and the value from the - operation as its second argument ('function(err, value){ }'). - @param {Boolean|Array} argumentNames An optional paramter that if set - to `true` causes the promise to fulfill with the callback's success arguments - as an array. This is useful if the node function has multiple success - paramters. If you set this paramter to an array with names, the promise will - fulfill with a hash with these names as keys and the success parameters as - values. - @return {Function} a function that wraps `nodeFunc` to return an - `RSVP.Promise` - @static - */ - __exports__["default"] = function denodeify(nodeFunc, options) { - var fn = function() { - var self = this; - var l = arguments.length; - var args = new Array(l + 1); - var arg; - var promiseInput = false; - - for (var i = 0; i < l; ++i) { - arg = arguments[i]; - - if (!promiseInput) { - // TODO: clean this up - promiseInput = needsPromiseInput(arg); - if (promiseInput === GET_THEN_ERROR) { - var p = new Promise(noop); - reject(p, GET_THEN_ERROR.value); - return p; - } else if (promiseInput && promiseInput !== true) { - arg = wrapThenable(promiseInput, arg); - } - } - args[i] = arg; - } - - var promise = new Promise(noop); - - args[l] = function(err, val) { - if (err) - reject(promise, err); - else if (options === undefined) - resolve(promise, val); - else if (options === true) - resolve(promise, arrayResult(arguments)); - else if (isArray(options)) - resolve(promise, makeObject(arguments, options)); - else - resolve(promise, val); - }; - - if (promiseInput) { - return handlePromiseInput(promise, args, nodeFunc, self); - } else { - return handleValueInput(promise, args, nodeFunc, self); - } - }; - - fn.__proto__ = nodeFunc; - - return fn; - } - - function handleValueInput(promise, args, nodeFunc, self) { - var result = tryApply(nodeFunc, self, args); - if (result === ERROR) { - reject(promise, result.value); - } - return promise; - } - - function handlePromiseInput(promise, args, nodeFunc, self){ - return Promise.all(args).then(function(args){ - var result = tryApply(nodeFunc, self, args); - if (result === ERROR) { - reject(promise, result.value); - } - return promise; - }); - } - - function needsPromiseInput(arg) { - if (arg && typeof arg === 'object') { - if (arg.constructor === Promise) { - return true; - } else { - return getThen(arg); - } - } else { - return false; - } - } - }); -enifed("rsvp/promise-hash", - ["./enumerator","./-internal","./utils","exports"], - function(__dependency1__, __dependency2__, __dependency3__, __exports__) { - "use strict"; - var Enumerator = __dependency1__["default"]; - var PENDING = __dependency2__.PENDING; - var o_create = __dependency3__.o_create; - - function PromiseHash(Constructor, object, label) { - this._superConstructor(Constructor, object, true, label); - } - - __exports__["default"] = PromiseHash; - - PromiseHash.prototype = o_create(Enumerator.prototype); - PromiseHash.prototype._superConstructor = Enumerator; - PromiseHash.prototype._init = function() { - this._result = {}; - }; - - PromiseHash.prototype._validateInput = function(input) { - return input && typeof input === 'object'; - }; - - PromiseHash.prototype._validationError = function() { - return new Error('Promise.hash must be called with an object'); - }; - - PromiseHash.prototype._enumerate = function() { - var promise = this.promise; - var input = this._input; - var results = []; - - for (var key in input) { - if (promise._state === PENDING && input.hasOwnProperty(key)) { - results.push({ - position: key, - entry: input[key] - }); - } - } - - var length = results.length; - this._remaining = length; - var result; - - for (var i = 0; promise._state === PENDING && i < length; i++) { - result = results[i]; - this._eachEntry(result.entry, result.position); - } - }; - }); -enifed("rsvp/promise", - ["./config","./instrument","./utils","./-internal","./promise/all","./promise/race","./promise/resolve","./promise/reject","exports"], - function(__dependency1__, __dependency2__, __dependency3__, __dependency4__, __dependency5__, __dependency6__, __dependency7__, __dependency8__, __exports__) { - "use strict"; - var config = __dependency1__.config; - var instrument = __dependency2__["default"]; - - var isFunction = __dependency3__.isFunction; - var now = __dependency3__.now; - - var noop = __dependency4__.noop; - var subscribe = __dependency4__.subscribe; - var initializePromise = __dependency4__.initializePromise; - var invokeCallback = __dependency4__.invokeCallback; - var FULFILLED = __dependency4__.FULFILLED; - var REJECTED = __dependency4__.REJECTED; - - var all = __dependency5__["default"]; - var race = __dependency6__["default"]; - var Resolve = __dependency7__["default"]; - var Reject = __dependency8__["default"]; - - var guidKey = 'rsvp_' + now() + '-'; - var counter = 0; - - function needsResolver() { - throw new TypeError('You must pass a resolver function as the first argument to the promise constructor'); - } - - function needsNew() { - throw new TypeError("Failed to construct 'Promise': Please use the 'new' operator, this object constructor cannot be called as a function."); - } - __exports__["default"] = Promise; - /** - Promise objects represent the eventual result of an asynchronous operation. The - primary way of interacting with a promise is through its `then` method, which - registers callbacks to receive either a promise’s eventual value or the reason - why the promise cannot be fulfilled. - - Terminology - ----------- - - - `promise` is an object or function with a `then` method whose behavior conforms to this specification. - - `thenable` is an object or function that defines a `then` method. - - `value` is any legal JavaScript value (including undefined, a thenable, or a promise). - - `exception` is a value that is thrown using the throw statement. - - `reason` is a value that indicates why a promise was rejected. - - `settled` the final resting state of a promise, fulfilled or rejected. - - A promise can be in one of three states: pending, fulfilled, or rejected. - - Promises that are fulfilled have a fulfillment value and are in the fulfilled - state. Promises that are rejected have a rejection reason and are in the - rejected state. A fulfillment value is never a thenable. - - Promises can also be said to *resolve* a value. If this value is also a - promise, then the original promise's settled state will match the value's - settled state. So a promise that *resolves* a promise that rejects will - itself reject, and a promise that *resolves* a promise that fulfills will - itself fulfill. - - - Basic Usage: - ------------ - - ```js - var promise = new Promise(function(resolve, reject) { - // on success - resolve(value); - - // on failure - reject(reason); - }); - - promise.then(function(value) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Advanced Usage: - --------------- - - Promises shine when abstracting away asynchronous interactions such as - `XMLHttpRequest`s. - - ```js - function getJSON(url) { - return new Promise(function(resolve, reject){ - var xhr = new XMLHttpRequest(); - - xhr.open('GET', url); - xhr.onreadystatechange = handler; - xhr.responseType = 'json'; - xhr.setRequestHeader('Accept', 'application/json'); - xhr.send(); - - function handler() { - if (this.readyState === this.DONE) { - if (this.status === 200) { - resolve(this.response); - } else { - reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']')); - } - } - }; - }); - } - - getJSON('/posts.json').then(function(json) { - // on fulfillment - }, function(reason) { - // on rejection - }); - ``` - - Unlike callbacks, promises are great composable primitives. - - ```js - Promise.all([ - getJSON('/posts'), - getJSON('/comments') - ]).then(function(values){ - values[0] // => postsJSON - values[1] // => commentsJSON - - return values; - }); - ``` - - @class RSVP.Promise - @param {function} resolver - @param {String} label optional string for labeling the promise. - Useful for tooling. - @constructor - */ - function Promise(resolver, label) { - this._id = counter++; - this._label = label; - this._state = undefined; - this._result = undefined; - this._subscribers = []; - - if (config.instrument) { - instrument('created', this); - } - - if (noop !== resolver) { - if (!isFunction(resolver)) { - needsResolver(); - } - - if (!(this instanceof Promise)) { - needsNew(); - } - - initializePromise(this, resolver); - } - } - - Promise.cast = Resolve; // deprecated - Promise.all = all; - Promise.race = race; - Promise.resolve = Resolve; - Promise.reject = Reject; - - Promise.prototype = { - constructor: Promise, - - _guidKey: guidKey, - - _onerror: function (reason) { - config.trigger('error', reason); - }, - - /** - The primary way of interacting with a promise is through its `then` method, - which registers callbacks to receive either a promise's eventual value or the - reason why the promise cannot be fulfilled. - - ```js - findUser().then(function(user){ - // user is available - }, function(reason){ - // user is unavailable, and you are given the reason why - }); - ``` - - Chaining - -------- - - The return value of `then` is itself a promise. This second, 'downstream' - promise is resolved with the return value of the first promise's fulfillment - or rejection handler, or rejected if the handler throws an exception. - - ```js - findUser().then(function (user) { - return user.name; - }, function (reason) { - return 'default name'; - }).then(function (userName) { - // If `findUser` fulfilled, `userName` will be the user's name, otherwise it - // will be `'default name'` - }); - - findUser().then(function (user) { - throw new Error('Found user, but still unhappy'); - }, function (reason) { - throw new Error('`findUser` rejected and we're unhappy'); - }).then(function (value) { - // never reached - }, function (reason) { - // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'. - // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'. - }); - ``` - If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream. - - ```js - findUser().then(function (user) { - throw new PedagogicalException('Upstream error'); - }).then(function (value) { - // never reached - }).then(function (value) { - // never reached - }, function (reason) { - // The `PedgagocialException` is propagated all the way down to here - }); - ``` - - Assimilation - ------------ - - Sometimes the value you want to propagate to a downstream promise can only be - retrieved asynchronously. This can be achieved by returning a promise in the - fulfillment or rejection handler. The downstream promise will then be pending - until the returned promise is settled. This is called *assimilation*. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // The user's comments are now available - }); - ``` - - If the assimliated promise rejects, then the downstream promise will also reject. - - ```js - findUser().then(function (user) { - return findCommentsByAuthor(user); - }).then(function (comments) { - // If `findCommentsByAuthor` fulfills, we'll have the value here - }, function (reason) { - // If `findCommentsByAuthor` rejects, we'll have the reason here - }); - ``` - - Simple Example - -------------- - - Synchronous Example - - ```javascript - var result; - - try { - result = findResult(); - // success - } catch(reason) { - // failure - } - ``` - - Errback Example - - ```js - findResult(function(result, err){ - if (err) { - // failure - } else { - // success - } - }); - ``` - - Promise Example; - - ```javascript - findResult().then(function(result){ - // success - }, function(reason){ - // failure - }); - ``` - - Advanced Example - -------------- - - Synchronous Example - - ```javascript - var author, books; - - try { - author = findAuthor(); - books = findBooksByAuthor(author); - // success - } catch(reason) { - // failure - } - ``` - - Errback Example - - ```js - - function foundBooks(books) { - - } - - function failure(reason) { - - } - - findAuthor(function(author, err){ - if (err) { - failure(err); - // failure - } else { - try { - findBoooksByAuthor(author, function(books, err) { - if (err) { - failure(err); - } else { - try { - foundBooks(books); - } catch(reason) { - failure(reason); - } - } - }); - } catch(error) { - failure(err); - } - // success - } - }); - ``` - - Promise Example; - - ```javascript - findAuthor(). - then(findBooksByAuthor). - then(function(books){ - // found books - }).catch(function(reason){ - // something went wrong - }); - ``` - - @method then - @param {Function} onFulfilled - @param {Function} onRejected - @param {String} label optional string for labeling the promise. - Useful for tooling. - @return {Promise} - */ - then: function(onFulfillment, onRejection, label) { - var parent = this; - var state = parent._state; - - if (state === FULFILLED && !onFulfillment || state === REJECTED && !onRejection) { - if (config.instrument) { - instrument('chained', this, this); - } - return this; - } - - parent._onerror = null; - - var child = new this.constructor(noop, label); - var result = parent._result; - - if (config.instrument) { - instrument('chained', parent, child); - } - - if (state) { - var callback = arguments[state - 1]; - config.async(function(){ - invokeCallback(state, child, callback, result); - }); - } else { - subscribe(parent, child, onFulfillment, onRejection); - } - - return child; - }, - - /** - `catch` is simply sugar for `then(undefined, onRejection)` which makes it the same - as the catch block of a try/catch statement. - - ```js - function findAuthor(){ - throw new Error('couldn't find that author'); - } - - // synchronous - try { - findAuthor(); - } catch(reason) { - // something went wrong - } - - // async with promises - findAuthor().catch(function(reason){ - // something went wrong - }); - ``` - - @method catch - @param {Function} onRejection - @param {String} label optional string for labeling the promise. - Useful for tooling. - @return {Promise} - */ - 'catch': function(onRejection, label) { - return this.then(null, onRejection, label); - }, - - /** - `finally` will be invoked regardless of the promise's fate just as native - try/catch/finally behaves - - Synchronous example: - - ```js - findAuthor() { - if (Math.random() > 0.5) { - throw new Error(); - } - return new Author(); - } - - try { - return findAuthor(); // succeed or fail - } catch(error) { - return findOtherAuther(); - } finally { - // always runs - // doesn't affect the return value - } - ``` - - Asynchronous example: - - ```js - findAuthor().catch(function(reason){ - return findOtherAuther(); - }).finally(function(){ - // author was either found, or not - }); - ``` - - @method finally - @param {Function} callback - @param {String} label optional string for labeling the promise. - Useful for tooling. - @return {Promise} - */ - 'finally': function(callback, label) { - var constructor = this.constructor; - - return this.then(function(value) { - return constructor.resolve(callback()).then(function(){ - return value; - }); - }, function(reason) { - return constructor.resolve(callback()).then(function(){ - throw reason; - }); - }, label); - } - }; - }); -enifed("rsvp/promise/all", - ["../enumerator","exports"], - function(__dependency1__, __exports__) { - "use strict"; - var Enumerator = __dependency1__["default"]; - - /** - `RSVP.Promise.all` accepts an array of promises, and returns a new promise which - is fulfilled with an array of fulfillment values for the passed promises, or - rejected with the reason of the first passed promise to be rejected.
