211 * Connects a new Route in the router.
212 *
213 * Routes are a way of connecting request urls to objects in your application. At their core routes
214 * are a set or regular expressions that are used to match requests to destinations.
215 *
216 * Examples:
217 *
218 * `Router::connect('/:controller/:action/*');`
219 *
220 * The first parameter will be used as a controller name while the second is used as the action name.
221 * the '/*' syntax makes this route greedy in that it will match requests like `/posts/index` as well as requests
222 * like `/posts/edit/1/foo/bar`.
223 *
224 * `Router::connect('/home-page', array('controller' => 'pages', 'action' => 'display', 'home'));`
225 *
226 * The above shows the use of route parameter defaults. And providing routing parameters for a static route.
227 *
228 * {{{
229 * Router::connect(
230 * '/:lang/:controller/:action/:id',
231 * array(),
232 * array('id' => '[0-9]+', 'lang' => '[a-z]{3}')
233 * );
234 * }}}
235 *
236 * Shows connecting a route with custom route parameters as well as providing patterns for those parameters.
237 * Patterns for routing parameters do not need capturing groups, as one will be added for each route params.
238 *
239 * $options offers three 'special' keys. `pass`, `persist` and `routeClass` have special meaning in the $options array.
240 *
241 * `pass` is used to define which of the routed parameters should be shifted into the pass array. Adding a
242 * parameter to pass will remove it from the regular route array. Ex. `'pass' => array('slug')`
243 *
244 * `persist` is used to define which route parameters should be automatically included when generating
245 * new urls. You can override persistent parameters by redefining them in a url or remove them by
246 * setting the parameter to `false`. Ex. `'persist' => array('lang')`
247 *
248 * `routeClass` is used to extend and change how individual routes parse requests and handle reverse routing,
249 * via a custom routing class. Ex. `'routeClass' => 'SlugRoute'`
250 *
251 * @param string $route A string describing the template of the route
252 * @param array $defaults An array describing the default route parameters. These parameters will be used by default
253 * and can supply routing parameters that are not dynamic. See above.
254 * @param array $options An array matching the named elements in the route to regular expressions which that
255 * element should match. Also contains additional parameters such as which routed parameters should be
256 * shifted into the passed arguments, supplying patterns for routing parameters and supplying the name of a
257 * custom routing class.
