                  net.sf.mmm.util.event.base.AbstractMultiThreadedEventSource<E,L>

Type Parameters:

E - is the templated type of the events to send.

L - is the templated type of the listeners that can be registered here and that will receive the sent events.

All Implemented Interfaces:

EventSource<E,L>

public abstract class AbstractMultiThreadedEventSource<E extends Event,L extends EventListener<E>>
extends AbstractSynchronizedEventSource<E,L>

This class extends AbstractSynchronizedEventSource with the ability to send events asynchronous in separate Threads.

Since:

1.0.1

Constructor Detail

AbstractMultiThreadedEventSource

public AbstractMultiThreadedEventSource()

The constructor.

Method Detail

setExecutor

@Inject
public void setExecutor(Executor threadPool)

This method sets the executor to use.

Parameters:

threadPool - is used to dispatch events in separate threads.

getExecutor

public Executor getExecutor()

This method gets the Executor used to run asynchronous tasks. It may use a thread-pool.

Returns:

the executor.

doInitialize

protected void doInitialize()

This method performs the actual initialization. It is called when AbstractComponent.initialize() is invoked for the first time.
ATTENTION:
When you override this method from a sub-class you need to do a super.AbstractComponent.doInitialize().

Overrides:

doInitialize in class AbstractLoggableComponent

fireEvent

protected void fireEvent(E event,
                         L listener)

This method sends the given event to the given listener.

Overrides:

fireEvent in class AbstractEventSource<E extends Event,L extends EventListener<E>>

Parameters:

event - the event to set.

listener - the listener that should receive the event.
