implements org.springframework.context.event.ApplicationEventMulticaster, org.springframework.context.ApplicationContextAware, MuleContextAware, Callable, Initialisable

MuleEventMulticaster is an implementation of a Spring ApplicationEventMulticaster. This implementation allows Mule event to be sent and received through the Spring ApplicationContext. This allows any Spring bean to receive and send events from any transport that Mule supports such as Jms, Http, Tcp, Pop3, Smtp, File, etc. All a bean needs to do to receive and send events is to implement MuleEventListener. Beans can also have subscriptions to certain events by implementing MuleSubscriptionEventListener, where the bean can provide a list of endpoints on which to receive events i.e. <bean id="myListener" class="com.foo.MyListener"> <property name="subscriptions"> <list> <value>jms://customer.support</value> <value>pop3://support:123456@mail.mycompany.com</value> </list> </property> </bean>

Endpoints are specified as a Mule Url which is used to register a listener for the subscription In the previous version of the MuleEventMulticaster it was possible to specify wildcard endpoints. This is still possible but you need to tell the multicaster which specific endpoints to listen on and then your subscription listeners can use wildcards. To register the specific endpoints on the MuleEvent Multicaster you use the subscriptions property.

<bean id="applicationEventMulticaster" class="org.mule.module.spring.events.MuleEventMulticaster"> <property name="subscriptions"> <list> <value>jms://orders.queue</value> <value>jms://another.orders.queue</value> </list> </property> </bean>

<bean id="myListener" class="com.foo.MyListener"> <property name="subscriptions"> <list> <value>jms://*.orders.*.</value> </list> </property> </bean>

Deprecated.

logger used by this class

asyncPool

protected ExecutorService asyncPool

Deprecated.

An ExecutorService for handling asynchronous events

subscriptions

protected String[] subscriptions

Deprecated.

A list of endpoints the eventMulticaster will receive events on Note that if this eventMulticaster has a Mule Descriptor associated with it, these endpoints are ignored and the ones on the Mule Descriptor are used. These are here for convenience, the event multicaster will use these to create a default MuleDescriptor for itself at runtime

Method Detail

setMuleContext

public void setMuleContext(MuleContext context)

Deprecated.

Specified by:

setMuleContext in interface MuleContextAware

initialise

public void initialise()
                throws InitialisationException

Deprecated.

Specified by:

initialise in interface Initialisable

Throws:

InitialisationException

addApplicationListener

public void addApplicationListener(org.springframework.context.ApplicationListener listener)

Deprecated.

Adds a listener to the the Multicaster. If asynchronous is set to true, an AsynchronousMessageListener is used to wrap the listener. This listener will be initialised with a threadpool. The configuration for the threadpool can be set on this multicaster or inherited from the MuleManager configuration, which is good for most cases.

Specified by:

addApplicationListener in interface org.springframework.context.event.ApplicationEventMulticaster

Parameters:

listener - the ApplicationListener to register with this Multicaster

See Also:

AsynchronousEventListener, ThreadingProfile

removeApplicationListener

public void removeApplicationListener(org.springframework.context.ApplicationListener listener)

Deprecated.

Removes a listener from the multicaster

Specified by:

removeApplicationListener in interface org.springframework.context.event.ApplicationEventMulticaster

Parameters:

listener - the listener to remove

addApplicationListenerBean

public void addApplicationListenerBean(String s)

Deprecated.

Specified by:

addApplicationListenerBean in interface org.springframework.context.event.ApplicationEventMulticaster

removeAllListeners

public void removeAllListeners()

Deprecated.

Removes all the listeners from the multicaster

Specified by:

removeAllListeners in interface org.springframework.context.event.ApplicationEventMulticaster

multicastEvent

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

Deprecated.

Method is used to dispatch events to listeners registered with the EventManager or dispatches events to Mule depending on the type and state of the event received. If the event is not a Mule event it will be dispatched to any listeners registered that are NOT MuleEventListeners. If the event is a Mule event and there is no source event attached to it, it is assumed that the event was dispatched by an object in the context using context.publishEvent() and will be dispatched by Mule. If the event does have a source event attached to it, it is assumed that the event was dispatched by Mule and will be delivered to any listeners subscribed to the event.

Specified by:

Parameters:

e - the application event received by the context
