方法详细资料

addEventListener

public void addEventListener(EventListener<?> listener)
                      throws java.lang.NullPointerException,
                             java.lang.IllegalArgumentException

从接口复制的说明: Listenable

Add a event listener

指定者:

addEventListener 在接口中 Listenable<EventListener<?>>

参数:

listener - a event listener If current EventListener is existed, return false

抛出:

java.lang.NullPointerException - if listener argument is null

java.lang.IllegalArgumentException - if listener argument is not concrete instance

removeEventListener

public void removeEventListener(EventListener<?> listener)
                         throws java.lang.NullPointerException,
                                java.lang.IllegalArgumentException

从接口复制的说明: Listenable

Remove a event listener

指定者:

removeEventListener 在接口中 Listenable<EventListener<?>>

参数:

listener - a event listener

抛出:

java.lang.NullPointerException - if listener argument is null

java.lang.IllegalArgumentException

getAllEventListeners

public java.util.List<EventListener<?>> getAllEventListeners()

从接口复制的说明: Listenable

Get all registered event listeners

指定者:

getAllEventListeners 在接口中 Listenable<EventListener<?>>

返回:

non-null read-only ordered event listeners

另请参阅:

EventListener.getPriority()

sortedListeners

protected java.util.stream.Stream<EventListener> sortedListeners()

sortedListeners

protected java.util.stream.Stream<EventListener> sortedListeners(java.util.function.Predicate<java.util.Map.Entry<java.lang.Class<? extends Event>,java.util.List<EventListener>>> predicate)

dispatch

public void dispatch(Event event)

从接口复制的说明: EventDispatcher

Dispatch a event to the registered event listeners

指定者:

dispatch 在接口中 EventDispatcher

参数:

event - a event

getExecutor

public final java.util.concurrent.Executor getExecutor()

从接口复制的说明: EventDispatcher

The Executor to dispatch a event

指定者:

getExecutor 在接口中 EventDispatcher

返回:

the non-null Executor

EventDispatcher.DIRECT_EXECUTOR

doInListener

protected void doInListener(EventListener<?> listener,
                            java.util.function.Consumer<java.util.Collection<EventListener>> consumer)

loadEventListenerInstances

protected void loadEventListenerInstances()

Default, load the instances of event listeners by ServiceLoader

It could be override by the sub-class
