- Type Parameters:
EVENT
-
public abstract class EventReactOnce<EVENT extends IWorldEvent>
- extends EventReact<EVENT>
This abstract class allows you to easily hook a specific event-handling behavior. It automatically
register a listener for a specified IWorldEvent
for you and calls EventReact.react(IWorldEvent)
method automatically. The EventReact.react(IWorldEvent)
will be called only once (upon first event received).
If you need to react every time, use EventReact
.
Use EventReact.enable()
and EventReact.disable()
to enable react / disable react. The reaction is enabled
as default.
WARNING:Use as anonymous class, but save it as a field of your class! Note, that we're using weak-references to
listeners and if you do not save pointer to the object, it will be gc()ed!
