Class BroadleafApplicationEventMulticaster

java.lang.Object

org.springframework.context.event.AbstractApplicationEventMulticaster

org.springframework.context.event.SimpleApplicationEventMulticaster

org.broadleafcommerce.common.event.BroadleafApplicationEventMulticaster

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.context.ApplicationContextAware, org.springframework.context.event.ApplicationEventMulticaster

public class BroadleafApplicationEventMulticaster
extends org.springframework.context.event.SimpleApplicationEventMulticaster
implements org.springframework.context.ApplicationContextAware

This class is a simple extension to Spring's SimpleApplicationEventMulticaster. The difference is that this allows the EventListener to indicate whether it should be asynchronous or not, assuming that a TaskExecutor has been configured. Asynchronous execution should be used with care. Events are not durable with this implementation. In addition, this implementation does not broadcast or multicast events to systems outside of the running JVM, although an event listener could be configured to do just that.

Method Detail

multicastEvent

public void multicastEvent(org.springframework.context.ApplicationEvent event)

Take care when specifying that event or application listener should be executed asynchronously. If there is no TaskExecutor configured, this will execute synchronously, regardless. If there is a TaskExecutor configured, then if the listener is a BroadleafApplicationListener and its isAsynchronous() method returns true then the event will fire asynchronously. Be aware that the events are not durable in this case. Events that are executed asynchronously should be used with caution, where a loss of event due to error or shutdown of the VM is not a major concern.
