Properties

$_emptyEventArgsInstance

Single instance of EventArgs.

private static EventArgs|null $_emptyEventArgsInstance

Methods

getEmptyInstance()

Gets the single, empty and immutable EventArgs instance.

public static getEmptyInstance() : EventArgs

This instance will be used when events are dispatched without any parameter, like this: EventManager::dispatchEvent('eventname');

The benefit from this is that only one empty instance is instantiated and shared (otherwise there would be instances for every dispatched in the abovementioned form).
