Method Detail

addEventListener

public void addEventListener(ClientEventListener cel)

Description copied from interface: ClientEventProducer

Adds an EventListener that will receive all events produced by the implementing object.

Specified by:

addEventListener in interface ClientEventProducer

Parameters:

cel - The ClientEventListener to add.

removeEventListener

public boolean removeEventListener(ClientEventListener cel)

Description copied from interface: ClientEventProducer

Removes an EventListener that will no loger receive events produced by the implementing object.

Specified by:

removeEventListener in interface ClientEventProducer

produceEvent

public void produceEvent(ClientEvent ce,
                         ClientContext context)

Sends the ClientEvent to all registered listeners of this object. Please do not change SimpleEventProducer to always produce events off-thread, it is better to run the client layer method that produces the event off-thread, because events could be re-ordered, which matters for some events notably SimpleProgressEvent. See e.g. ClientGetter.innerNotifyClients()),

Specified by:

produceEvent in interface ClientEventProducer

Parameters:

ce - the ClientEvent to raise

getEventListeners

public ClientEventListener[] getEventListeners()

Returns the listeners as an array.

addEventListeners

public void addEventListeners(ClientEventListener[] cela)
