Method Summary

Modifier and Type	Method and Description
void	afterPropertiesSet() If registered as bean in spring context, we need to get the tenantService in case we register this listener with EventService#registerEventListener(org.springframework.context.ApplicationListener) it is done in inside the method.
void	onApplicationEvent(T event) The given ApplicationEvent has to be an instance of an AbstractEvent and must be addressed to the current cluster.
protected abstract void	onEvent(T event) This method is called by AbstractEventListener#onApplicationEvent(ApplicationEvent) and processes the given event.
void	setApplicationContext(ApplicationContext applicationContext) Only called in case this bean is registered in ApplicationContext we need the applicationContext in afterPropertiesSet() to get the TenantService.
void	setClusterService(ClusterService clusterService) Called either when registering with EventService.registerEventListener or when registering this bean in the spring context.
void	setTenantService(TenantService tenantService) Called either when registering with EventService.registerEventListener or when registering this bean in the spring context.

Method Detail

onApplicationEvent

public final void onApplicationEvent(T event)

onEvent

protected abstract void onEvent(T event)

This method is called by AbstractEventListener#onApplicationEvent(ApplicationEvent) and processes the given event.

event - the event to be processed

#onApplicationEvent(ApplicationEvent)

setTenantService

public void setTenantService(TenantService tenantService)

Called either when registering with EventService.registerEventListener or when registering this bean in the spring context. If you forget to inject the TenantService it is set from within the afterPropertiesSet() method (see there). This is for your convenience.

setClusterService

public void setClusterService(ClusterService clusterService)

Called either when registering with EventService.registerEventListener or when registering this bean in the spring context. If you forget to inject the ClusterService it is set from within the afterPropertiesSet() method (see there). This is for your convenience.

setApplicationContext

public void setApplicationContext(ApplicationContext applicationContext)

Only called in case this bean is registered in ApplicationContext we need the applicationContext in afterPropertiesSet() to get the TenantService.

afterPropertiesSet

public void afterPropertiesSet()

If registered as bean in spring context, we need to get the tenantService in case we register this listener with EventService#registerEventListener(org.springframework.context.ApplicationListener) it is done in inside the method.
