从接口继承的方法 cn.taketoday.context.event.GenericApplicationListener

supportsEventType

构造器详细资料

GenericApplicationListenerAdapter

public GenericApplicationListenerAdapter(ApplicationListener delegate)

Create a new GenericApplicationListener for the given delegate.

参数:

delegate - the delegate listener to be invoked

方法详细资料

onApplicationEvent

public void onApplicationEvent(ApplicationEvent event)

从接口复制的说明: ApplicationListener

Handle an application event.

指定者:

onApplicationEvent 在接口中 ApplicationListener<ApplicationEvent>

参数:

event - the event to respond to

supportsEventType

public boolean supportsEventType(cn.taketoday.core.ResolvableType eventType)

从接口复制的说明: GenericApplicationListener

Determine whether this listener actually supports the given event type.

指定者:

supportsEventType 在接口中 GenericApplicationListener

参数:

eventType - the event type (never null)

supportsSourceType

public boolean supportsSourceType(@Nullable
 Class<?> sourceType)

从接口复制的说明: SmartApplicationListener

Determine whether this listener actually supports the given source type.

The default implementation always returns true.

指定者:

supportsSourceType 在接口中 SmartApplicationListener

参数:

sourceType - the source type, or null if no source

getOrder

public int getOrder()

从接口复制的说明: SmartApplicationListener

Determine this listener's order in a set of listeners for the same event.

The default implementation returns Ordered.LOWEST_PRECEDENCE.

指定者:

getOrder 在接口中 cn.taketoday.core.Ordered

指定者:

getOrder 在接口中 SmartApplicationListener

getListenerId

public String getListenerId()

从接口复制的说明: SmartApplicationListener

Return an optional identifier for the listener.

The default value is an empty String.

指定者:

getListenerId 在接口中 SmartApplicationListener
