Response
boolTrue, if the file has successfully loaded.
registerLegacyListener
Registers a legacy event listener, i.e. a method which accepts individual arguments instead of an AbstractEvent in its arguments. This provides backwards compatibility to Joomla! 3.x-style plugins.
registerLegacyListener( methodName) :
This method will register lambda functions (closures) which try to unwrap the arguments of the dispatched Event into old style method arguments and call your on<Something> method with them. The result will be passed back to the Event, as an element into an array argument called 'result'.

Response
void
registerListener
Registers a proper event listener, i.e. a method which accepts an AbstractEvent as its sole argument. This is the preferred way to implement plugins in Joomla! 4.x and will be the only possible method with Joomla! 5.x onwards.
registerListener( methodName) :

Arguments
- methodName
stringThe method name to register
Response
void
registerListeners
Registers legacy Listeners to the Dispatcher, emulating how plugins worked under Joomla! 3.x and below.
registerListeners() :
By default, this method will look for all public methods whose name starts with "on". It will register lambda functions (closures) which try to unwrap the arguments of the dispatched Event into method call arguments and call your on<Something> method. The result will be passed back to the Event into its 'result' argument.
This method additionally supports Joomla\Event\SubscriberInterface and plugins implementing this will be registered to the dispatcher as a subscriber.

autoloadLanguage
If true, language files of the plugin will be loaded automatically.
NOTE: Enabling this feature have a negative effect on performance, therefore it is recommended to load a language manually, in the respective event.

allowLegacyListeners
Should I try to detect and register legacy event listeners, i.e. methods which accept unwrapped arguments? While this maintains a great degree of backwards compatibility to Joomla! 3.x-style plugins it is much slower. You are advised to implement your plugins using proper Listeners, methods accepting an AbstractEvent as their sole parameter, for best performance. Also bear in mind that Joomla! 5.x onwards will only allow proper listeners, removing support for legacy Listeners.
