* {@link org.springframework.context.ApplicationListener} extended interface capable of invoking
* <b>Event Driven POJOs</b> (<b>EDP</b>): plain old Java objects with methods that have to be invoked upon
* certain events.
* <br>
* EDPInvoker implementations will have to define:
* <ul>
* <li>The invoked EDP bean (see {@link #getInvokedBean()}), often defined in the Spring application context.</li>
* <li>The name of the method to invoke on the bean defined above (see {@link #getInvokedMethodName()});
* if the bean has more overloaded methods with the same name above, all of these methods will be invoked.</li>
* </ul>
* Implementors will have to define the actual invoking strategy, by specifying what {@link org.springframework.context.ApplicationEvent}s
* cause the bean methods to be invoked, and how to invoke them.
