Record Class PageEventHandler.HandlerMethod<T extends javafx.event.Event>

java.lang.Object
java.lang.Record
gui.page.PageEventHandler.HandlerMethod<T>
Enclosing interface:
PageEventHandler
public static record PageEventHandler.HandlerMethod<T extends javafx.event.Event>(javafx.event.EventType<T extends javafx.event.Event> eventType, javafx.event.EventHandler<? super T extends javafx.event.Event> eventHandler) extends Record
Combination of an EventType and an EventHandler which handles events of an appropriate type.

The type for this class looks intimidating, but its usage is fairly straightforward. Its purpose is simply to couple an EventType with an EventHandler so that they can easily be passed around together.

In the following example, a HandlerMethod is created which will accept all types of events and print them: 

 new HandlerMethod(Event.ANY, e -> System.out.println(e));
