PSR-14: Event Dispatching

TYPO3

Beschreibung

This skill covers the basics of the PHP standard on Event dispatching.

I know the four use cases of events specified by PSR-14.
I know about the different components of a PSR-14-compliant event system (Listener, Emitter, Dispatcher, ListenerProvider).
I know when mutable or immutable events should be used.
