OneShotEvent.java

public final class OneShotEvent<T extends Event>
    implements EventHandler<T>
{
    private final AtomicBoolean triggered = new AtomicBoolean(false);
    private final EventHandler<T> delegate;
    
    public static <E extends Event> EventHandler<E> of(final EventHandler<E> delegate)
    {
        return new OneShotEvent<>(delegate);
    }
    
    private OneShotEvent(final EventHandler<T> delegate)

    }
    
    @Override
    public void handle(final T event)
    {
        if (!triggered.getAndSet(true))
            delegate.handle(event);
