DeferredApplicationEventPublisher (Microsphere :: Spring :: Context 0.1.2 API)

java.lang.Object
- io.microsphere.spring.context.event.DeferredApplicationEventPublisher

All Implemented Interfaces:

java.util.EventListener, org.springframework.context.ApplicationEventPublisher, org.springframework.context.ApplicationListener<org.springframework.context.event.ContextRefreshedEvent>
```
@Deprecated
public class DeferredApplicationEventPublisher
extends java.lang.Object
implements org.springframework.context.ApplicationEventPublisher, org.springframework.context.ApplicationListener<org.springframework.context.event.ContextRefreshedEvent>
```
Deprecated.

Before Spring Framework 4.2, AbstractApplicationContext is an implementation of ApplicationEventPublisher can't handle the early event that is published before ApplicationEventMulticaster's initialization, in this scenario, DeferredApplicationEventPublisher is introduced and used to resolve publishEvent(ApplicationEvent) too early to publish ApplicationEvent when Spring ApplicationContexts' ApplicationEventMulticaster is not ready. First, DeferredApplicationEventPublisher stores these early events temporarily, and then re-publish them on Application context is ready.
In contrast, If current runtime is based on Spring Framework that supports early application events, DeferredApplicationEventPublisher only delegates the Application Context that was injected by constructor.

Since:

1.0.0
