| Method Summary | |
| public Object | interceptEvent(StaticJoinPoint jp, ApplicationEvent event, AbstractApplicationContext ctx)
Intercepts the sending of a spring ApplicationContext event, this advice captures it and
tries to publish it as a distributed event. | | public void | multicastEvent(String ctxId, ApplicationEvent event)
[Distributed Method Invocation]
1. | | public void | registerContext(StaticJoinPoint jp, AbstractApplicationContext ctx)
Puts all clustered ApplicationContext instances into a node local HashMap . | | public String | toString()
| | public boolean | tryToPublishDistributedEvent(BeanFactory beanFactory, ApplicationEvent event)
Tries to publish the event as a distributed event, by invoking a distributed method invocation. |
| interceptEvent | | public Object interceptEvent(StaticJoinPoint jp, ApplicationEvent event, AbstractApplicationContext ctx) throws Throwable(Code) | | Intercepts the sending of a spring ApplicationContext event, this advice captures it and
tries to publish it as a distributed event.
Invoked around void org.springframework.context.support.AbstractApplicationContext.publishEvent(..)
|
| multicastEvent | | public void multicastEvent(String ctxId, ApplicationEvent event)(Code) | | [Distributed Method Invocation]
1. Gets the context by ID - needed since the DMI is invoked on another node and
need to look up [it's context].
2. Publish event in the context matching the ID
|
| registerContext | | public void registerContext(StaticJoinPoint jp, AbstractApplicationContext ctx)(Code) | | Puts all clustered ApplicationContext instances into a node local HashMap .
Puts itself (the aspect) into a shared map, this is needed for DMI to work.
Puts some additional information into the aspect to be displayed as a regular info in the terracotta console.
