Public Constructors

public GenericApplicationListenerAdapter (ApplicationListener delegate)

Create a new GenericApplicationListener for the given delegate.

Parameters
delegate the delegate listener to be invoked

Public Methods

public int getOrder ()

Return the order value of this object, with a higher value meaning greater in terms of sorting.

Normally starting with 0, with Integer.MAX_VALUE indicating the greatest value. Same order values will result in arbitrary positions for the affected objects.

Higher values can be interpreted as lower priority. As a consequence, the object with the lowest value has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Returns
  • the order value

public void onApplicationEvent (ApplicationEvent event)

public boolean supportsEventType (Class<? extends ApplicationEvent> eventType)

Determine whether this listener actually supports the given event type.

public boolean supportsSourceType (Class<?> sourceType)

Determine whether this listener actually supports the given source type.
