Even when you don't use the views object + * explicitly on a state config, one is still created for you internally. + * So by decorating this builder function you have access to decorating template + * and controller properties. + * - **ownParams** `{object}` - returns an array of params that belong to the state, + * not including any params defined by ancestor states. + * - **path** `{string}` - returns the full path from the root down to this state. + * Needed for state activation. + * - **includes** `{object}` - returns an object that includes every state that + * would pass a `$state.includes()` test. + * + * @example + *

In the **`params`** + * map, instead mapping the param name to a full parameter configuration + * object, simply set map it to the default parameter value, e.g.: + * + * 
// define a parameter's default value
+   * params: {

+   * }
+ * + * - ** array ** - {boolean=}: *(default: false)* If true, the param value will be + * treated as an array of values. If you specified a Type, the value will be + * treated as an array of the specified Type. Note: query parameter values + * default to a special `"auto"` mode. + * + * For query parameters in `"auto"` mode, if multiple values for a single parameter + * are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values + * are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`). However, if + * only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single + * value (e.g.: `{ foo: '1' }`). + * + * 
params: {
+   *     param1: { array: true }
+   * }
+ * + * - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when + * the current parameter value is the same as the default value. If `squash` is not set, it uses the + * configured default squash policy. + * (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`}) + * + * There are three squash settings: + * + * - false: The parameter's default value is not squashed. It is encoded and included in the URL + * - true: The parameter's default value is omitted from the URL. If the parameter is preceeded and followed + * by slashes in the state's `url` declaration, then one of those slashes are omitted. + * This can allow for cleaner looking URLs. + * - `""`: The parameter's default value is replaced with an arbitrary placeholder of your choice. + * + *

+ * })
+ *
+ * + * But typically you'll only use the views property if you name your view or have more than one view + * in the same template. There's not really a compelling reason to name a view if its the only one, + * but you could if you wanted, like so: + * 
+ * 

+ *
+ *

+ *
+ * + * Really though, you'll use views to set up multiple views: + *

+ * 
 
+ * 
 
+ *
+ * + * 
+ * $stateProvider.state("home", {

IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO + NOT CONTROL. + + + This file creates a global JSON object containing two methods: stringify + and parse. + + JSON.stringify(value, replacer, space) + value any JavaScript value, usually an object or array. + + replacer an optional parameter that determines how object + values are stringified for objects. It can be a + function or an array of strings. + + space an optional parameter that specifies the indentation + of nested structures. If it is omitted, the text will + be packed without extra whitespace. If it is a number, + it will specify the number of spaces to indent at each + level. If it is a string (such as '\t' or ' '), + it contains the characters used to indent at each level. + + This method produces a JSON text from a JavaScript value. + + When an object value is found, if the object contains a toJSON + method, its toJSON method will be called and the result will be + stringified. A toJSON method does not serialize: it returns the + value represented by the name/value pair that should be serialized, + or undefined if nothing should be serialized.

It will be passed the + key and value of each member, with this bound to the containing + object. The value that is returned from your method will be + serialized. If your method returns undefined, then the member will + be excluded from the serialization. + + If the replacer parameter is an array of strings, then it will be + used to select the members to be serialized. It filters the results + such that only members with keys listed in the replacer array are + stringified. + + Values that do not have JSON representations, such as undefined or + functions, will not be serialized. Such values in objects will be + dropped; in arrays they will be replaced with null. You can use + a replacer function to replace those with JSON values. + JSON.stringify(undefined) returns undefined. + + The optional space parameter produces a stringification of the + value that is filled with line breaks and indentation to make it + easier to read. + + If the space parameter is a non-empty string, then that string will + be used for indentation. If the space parameter is a number, then + the indentation will be that many spaces. + + Example: + + text = JSON.stringify(['e', {pluribus: 'unum'}]); + // text is '["e",{"pluribus":"unum"}]' + + + text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); + // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' + + text = JSON.stringify([new Date()], function (key, value) { + return this[key] instanceof Date ? + 'Date(' + this[key] + ')' : value; + }); + // text is '["Date(---current time---)"]' + + + JSON.parse(text, reviver) + This method parses a JSON text to produce an object or array. + It can throw a SyntaxError exception. + + The optional reviver parameter is a function that can filter and + transform the results. It receives each of the keys and values, + and its return value is used instead of the original value. + If it returns what it received, then the structure is not modified. + If it returns undefined then the member is deleted. + + Example: + + // Parse the text.

+ * + * + * # Iterating over object properties + * + * It is possible to get `ngRepeat` to iterate over the properties of an object using the following + * syntax: + * + * ```js + *
...
+ * ``` + * + * However, there are a limitations compared to array iteration: + * + * - The JavaScript specification does not define the order of keys + * returned for an object, so Angular relies on the order returned by the browser + * when running `for key in myObj`. Browsers generally follow the strategy of providing + * keys in the order in which they were defined, although there are exceptions when keys are deleted + * and reinstated. See the + * [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes). + * + * - `ngRepeat` will silently *ignore* object keys starting with `$`, because + * it's a prefix used by Angular for public (`$`) and private (`$$`) properties. + * + * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with + * objects, and will throw an error if used with one. + * + * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array + * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could + * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter) + * or implement a `$watch` on the object yourself. + * + * + * # Tracking and Duplicates + * + * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in + * the collection. When a change happens, ngRepeat then makes the corresponding changes to the DOM: + * + * * When an item is added, a new instance of the template is added to the DOM. + * * When an item is removed, its template instance is removed from the DOM. + * * When items are reordered, their respective templates are reordered in the DOM. + * + * To minimize creation of DOM elements, `ngRepeat` uses a function + * to "keep track" of all items in the collection and their corresponding DOM elements. + * For example, if an item is added to the collection, ngRepeat will know that all other items + * already have DOM elements, and will not re-render them. + * + * The default tracking function (which tracks items by their identity) does not allow + * duplicate items in arrays. This is because when there are duplicates, it is not possible + * to maintain a one-to-one mapping between collection items and DOM elements. + * + * If you do need to repeat duplicate items, you can substitute the default tracking behavior + * with your own using the `track by` expression. + * + * For example, you may track items by the index of each item in the collection, using the + * special scope property `$index`: + * ```html + *
+ * {{n}} + *
+ * ``` + * + * You may also use arbitrary expressions in `track by`, including references to custom functions + * on the scope: + * ```html + *
+ * {{n}} + *
+ * ``` + * + *
+ * If you are working with objects that have an identifier property, you should track + * by the identifier instead of the whole object. Should you reload your data later, `ngRepeat` + * will not have to rebuild the DOM elements for items it has already rendered, even if the + * JavaScript objects in the collection have been substituted for new ones. For large collections, + * this significantly improves rendering performance. If you don't have a unique identifier, + * `track by $index` can also provide a performance boost. + *
+ * ```html + *
+ * {{model.name}} + *
+ * ``` + * + * When no `track by` expression is provided, it is equivalent to tracking by the built-in + * `$id` function, which tracks items by their identity: + * ```html + *
+ * {{obj.prop}} + *
+ * ``` + * + *

+ * ``` + * + * # Special repeat start and end points + * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending + * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively. + * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on) + * up to and including the ending HTML tag where **ng-repeat-end** is placed. + * + * The example below makes use of this feature: + * ```html + *
+ * Header {{ item }} + *
+ *
+ * Body {{ item }} + *
+ *
+ * Footer {{ item }} + *
+ * ``` + * + * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to: + * ```html + *
+ * Header A + *
+ *
+ * Body A + *
+ *
+ * Footer A + *
+ *
+ * Header B + *
+ *
+ * Body B + *
+ *
+ * Footer B + *
+ * ``` + * + * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such + * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**). + * + * @animations + * | Animation | Occurs | + * |----------------------------------|-------------------------------------| + * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter | + * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out | + * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered | + * + * See the example below for defining CSS animations with ngRepeat. + * + * @element ANY + * @scope + * @priority 1000 + * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These + * formats are currently supported: + * + * * `variable in expression` – where variable is the user defined loop variable and `expression` + * is a scope expression giving the collection to enumerate. + * + * For example: `album in artist.albums`. + * + * * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers, + * and `expression` is the scope expression giving the collection to enumerate. + * + * For example: `(name, age) in {'adam':10, 'amalie':12}`. + * + * * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression + * which can be used to associate the objects in the collection with the DOM elements. If no tracking expression + * is specified, ng-repeat associates elements by identity. It is an error to have + * more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are + * mapped to the same DOM element, which is not possible.) + * + * Note that the tracking expression must come last, after any filters, and the alias expression. + * + * For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements + * will be associated by item identity in the array. + * + * For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique + * `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements + * with the corresponding item in the array by identity. Moving the same object in array would move the DOM + * element in the same way in the DOM. + * + * For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this + * case the object identity does not matter. Two objects are considered equivalent as long as their `id` + * property is same. + * + * For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter + * to items in conjunction with a tracking expression. + * + * * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the + * intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message + * when a filter is active on the repeater, but the filtered result set is empty. + * + * For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after + * the items have been processed through the filter. + * + * Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end + * (and not as operator, inside an expression). + * + * For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` . + * + * @example + * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed + * results by name. New (entering) and removed (leaving) items are animated. + + +

In other words, you define a container element + * (where you place the directive), place an expression on the **`on="..."` attribute** + * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place + * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on + * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default + * attribute is displayed. + * + *
+ * Be aware that the attribute values to match against cannot be expressions. They are interpreted + * as literal string values to match against. + * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the + * value of the expression `$scope.someVal`. + *
