All characters are eagerly stored in `$routeParams` under the given `name` * when the route matches. * * `path` can contain optional named groups with a question mark: e.g.`:name?`. * * For example, routes like `/color/:color/largecode/:largecode*\/edit` will match * `/color/brown/largecode/code/with/slashes/edit` and extract: * * * `color: brown` * * `largecode: code/with/slashes`. * * * @param {Object} route Mapping information to be assigned to `$route.current` on route * match. * * Object properties: * * - `controller` – `{(string|Function)=}` – Controller fn that should be associated with * newly created scope or the name of a {@link angular.Module#controller registered * controller} if passed as a string. * - `controllerAs` – `{string=}` – An identifier name for a reference to the controller. * If present, the controller will be published to scope under the `controllerAs` name. * - `template` – `{(string|Function)=}` – html template as a string or a function that * returns an html template as a string which should be used by {@link * ngRoute.directive:ngView ngView} or {@link ng.directive:ngInclude ngInclude} directives. * This property takes precedence over `templateUrl`. * * If `template` is a function, it will be called with the following parameters: * * - `{Array.}` - route parameters extracted from the current * `$location.path()` by applying the current route * * One of `template` or `templateUrl` is required. * * - `templateUrl` – `{(string|Function)=}` – path or function that returns a path to an html * template that should be used by {@link ngRoute.directive:ngView ngView}. * * If `templateUrl` is a function, it will be called with the following parameters: * * - `{Array.}` - route parameters extracted from the current * `$location.path()` by applying the current route * * One of `templateUrl` or `template` is required. * * - `resolve` - `{Object.=}` - An optional map of dependencies which should * be injected into the controller. If any of these dependencies are promises, the router * will wait for them all to be resolved or one to be rejected before the controller is * instantiated. * If all the promises are resolved successfully, the values of the resolved promises are * injected and {@link ngRoute.$route#$routeChangeSuccess $routeChangeSuccess} event is * fired. If any of the promises are rejected the * {@link ngRoute.$route#$routeChangeError $routeChangeError} event is fired. * For easier access to the resolved dependencies from the template, the `resolve` map will * be available on the scope of the route, under `$resolve` (by default) or a custom name * specified by the `resolveAs` property (see below). This can be particularly useful, when * working with {@link angular.Module#component components} as route templates.
*
* **Note:** If your scope already contains a property with this name, it will be hidden * or overwritten. Make sure, you specify an appropriate name for this property, that * does not collide with other properties on the scope. *
* The map object is: * * - `key` – `{string}`: a name of a dependency to be injected into the controller. * - `factory` - `{string|Function}`: If `string` then it is an alias for a service. * Otherwise if function, then it is {@link auto.$injector#invoke injected} * and the return value is treated as the dependency. If the result is a promise, it is * resolved before its value is injected into the controller. Be aware that * `ngRoute.$routeParams` will still refer to the previous route within these resolve * functions. Use `$route.current.params` to access the new route parameters, instead. * * - `resolveAs` - `{string=}` - The name under which the `resolve` map will be available on * the scope of the route. If omitted, defaults to `$resolve`. * * - `redirectTo` – `{(string|Function)=}` – value to update * {@link ng.$location $location} path with and trigger route redirection. * * If `redirectTo` is a function, it will be called with the following parameters: * * - `{Object.}` - route parameters extracted from the current * `$location.path()` by applying the current route templateUrl. * - `{string}` - current `$location.path()` * - `{Object}` - current `$location.search()` * * The custom `redirectTo` function is expected to return a string which will be used * to update `$location.url()`. If the function throws an error, no further processing will * take place and the {@link ngRoute.$route#$routeChangeError $routeChangeError} event will * be fired. * * Routes that specify `redirectTo` will not have their controllers, template functions * or resolves called, the `$location` will be changed to the redirect url and route * processing will stop. The exception to this is if the `redirectTo` is a function that * returns `undefined`. In this case the route transition occurs as though there was no * redirection. * * - `resolveRedirectTo` – `{Function=}` – a function that will (eventually) return the value * to update {@link ng.$location $location} URL with and trigger route redirection. In * contrast to `redirectTo`, dependencies can be injected into `resolveRedirectTo` and the * return value can be either a string or a promise that will be resolved to a string. * * Similar to `redirectTo`, if the return value is `undefined` (or a promise that gets * resolved to `undefined`), no redirection takes place and the route transition occurs as * though there was no redirection. * * If the function throws an error or the returned promise gets rejected, no further * processing will take place and the * {@link ngRoute.$route#$routeChangeError $routeChangeError} event will be fired. * * `redirectTo` takes precedence over `resolveRedirectTo`, so specifying both on the same * route definition, will cause the latter to be ignored. * * - `[reloadOnSearch=true]` - `{boolean=}` - reload route when only `$location.search()` * or `$location.hash()` changes. * * If the option is set to `false` and url in the browser changes, then * `$routeUpdate` event is broadcasted on the root scope. * * - `[caseInsensitiveMatch=false]` - `{boolean=}` - match routes without being case sensitive * * If the option is set to `true`, then the particular route can be matched without being * case sensitive * * @returns {Object} self * * @description * Adds a new route definition to the `$route` service. */ this.when = function(path, route) { //copy original route object to preserve params inherited from proto chain var routeCopy = shallowCopy(route); if (angular.isUndefined(routeCopy.reloadOnSearch)) { routeCopy.reloadOnSearch = true; } if (angular.isUndefined(routeCopy.caseInsensitiveMatch)) { routeCopy.caseInsensitiveMatch = this.caseInsensitiveMatch; } routes[path] = angular.extend( routeCopy, path && pathRegExp(path, routeCopy) ); // create redirection for trailing slashes if (path) { var redirectPath = (path[path.length - 1] === '/') ? path.substr(0, path.length - 1) : path + '/'; routes[redirectPath] = angular.extend( {redirectTo: path}, pathRegExp(redirectPath, routeCopy) ); } return this; }; /** * @ngdoc property * @name $routeProvider#caseInsensitiveMatch * @description * * A boolean property indicating if routes defined * using this provider should be matched using a case insensitive * algorithm.
