    • supportsEventType

      boolean supportsEventType(Class<? extends ApplicationEvent> eventType)
      Determine whether this listener actually supports the given event type.
      参数:
      eventType - the event type (never null)

    • supportsSourceType

      default boolean supportsSourceType(@Nullable Class<?> sourceType)
      Determine whether this listener actually supports the given source type.

      The default implementation always returns true.

      参数:
      sourceType - the source type, or null if no source

    • getOrder

      default int getOrder()
      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

    • getListenerId

      default String getListenerId()
      Return an optional identifier for the listener.
