All Implemented Interfaces:

ApplicationEventMulticaster

public class SimpleApplicationEventMulticaster
extends AbstractApplicationEventMulticaster

Simple implementation of the ApplicationEventMulticaster interface.

Multicasts all events to all registered listeners, leaving it up to the listeners to ignore events that they are not interested in. Listeners will usually perform corresponding instanceof checks on the passed-in event object.

All listeners are invoked in the calling thread. This allows the danger of a rogue listener blocking the entire application, but adds minimal overhead.

An alternative implementation could be more sophisticated in both these respects.
