示例1: trigger
/**
* Trigger a callback method on every object in the collection.
* Used to trigger methods on objects in the collection. Will fire the methods in the
* order they were attached.
*
* ### Options
*
* - `breakOn` Set to the value or values you want the callback propagation to stop on.
* Can either be a scalar value, or an array of values to break on. Defaults to `false`.
*
* - `break` Set to true to enabled breaking. When a trigger is broken, the last returned value
* will be returned. If used in combination with `collectReturn` the collected results will be returned.
* Defaults to `false`.
*
* - `collectReturn` Set to true to collect the return of each object into an array.
* This array of return values will be returned from the trigger() call. Defaults to `false`.
*
* - `modParams` Allows each object the callback gets called on to modify the parameters to the next object.
* Setting modParams to an integer value will allow you to modify the parameter with that index.
* Any non-null value will modify the parameter index indicated.
* Defaults to false.
*
* @param string|CakeEvent $callback Method to fire on all the objects. Its assumed all the objects implement
* the method you are calling. If an instance of CakeEvent is provided, then then Event name will parsed to
* get the callback name. This is done by getting the last word after any dot in the event name
* (eg. `Model.afterSave` event will trigger the `afterSave` callback)
* @param array $params Array of parameters for the triggered callback.
* @param array $options Array of options.
* @return mixed Either the last result or all results if collectReturn is on.
* @throws CakeException when modParams is used with an index that does not exist.
