Package org.appng.core.domain

Class PlatformEventListener

java.lang.Object

org.appng.core.domain.PlatformEventListener

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

public class PlatformEventListener
extends Object
implements org.springframework.context.ApplicationContextAware

An entity listener that creates a new PlatformEvent on PrePersist, PreUpdate and PreRemove. Also, a PlatformEvent can be created manually by calling createEvent(PlatformEvent.Type, String).
Note that this listener is able to work in two scenarios. The first is as a regular Spring bean that can be invoked from other beans. As a JPA entity listener, we use a static reference to the current ApplicationContext to retrieve an instance of the EntityManager in use.
