Interface StatefulEventHandlerTemplate.StateTransitioningHandler<T,S,E extends javafx.event.Event>

Enclosing class:

StatefulEventHandlerTemplate<T,S,E extends javafx.event.Event>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface StatefulEventHandlerTemplate.StateTransitioningHandler<T,S,E extends javafx.event.Event>

An instance of this interface is expected to consume the event if it successfully handled the event. If the event was not handled by an instance of this interface, the event should be left unconsumed and the returned state should be unchanged.
