| __construct($name, &$data) X-Ref |
| event constructor param: string $name param: mixed $data |
| __toString() X-Ref |
return: string |
| advise_before($enablePreventDefault = true) X-Ref |
| advise all registered BEFORE handlers of this event if these methods are used by functions outside of this object, they must properly handle correct processing of any default action and issue an advise_after() signal. e.g. $evt = new dokuwiki\Plugin\Doku_Event(name, data); if ($evt->advise_before(canPreventDefault) { // default action code block } $evt->advise_after(); unset($evt); return: bool results of processing the event, usually $this->runDefault param: bool $enablePreventDefault |
| advise_after() X-Ref |
| advise all registered AFTER handlers of this event see: advise_before() for details param: bool $enablePreventDefault |
| trigger($action = null, $enablePrevent = true) X-Ref |
| trigger - advise all registered (<event>_BEFORE) handlers that this event is about to take place - carry out the default action using $this->data based on $enablePrevent and $this->_default, all of which may have been modified by the event handlers. - advise all registered (<event>_AFTER) handlers that the event has taken place return: mixed $event->results param: null|callable $action param: bool $enablePrevent |
| stopPropagation() X-Ref |
| stopPropagation stop any further processing of the event by event handlers this function does not prevent the default action taking place |
| mayPropagate() X-Ref |
| may the event propagate to the next handler? return: bool |
| preventDefault() X-Ref |
| preventDefault prevent the default action taking place |
| mayRunDefault() X-Ref |
| should the default action be executed? return: bool |
| createAndTrigger($name, &$data, $action = null, $canPreventDefault = true) X-Ref |
| Convenience method to trigger an event Creates, triggers and destroys an event in one go return: mixed the event results value after all event processing is complete param: string $name name for the event param: mixed $data event data param: callable $action (optional, default=NULL) default action, a php callback function param: bool $canPreventDefault (optional, default=true) can hooks prevent the default action |
