completed

public abstract void completed(AsyncResult r)

Parameters:

r - The asynchronous result object returned by the begin_OP method.

sent

public void sent(AsyncResult r)

Invoked when the Ice run time has passed the outgoing message buffer to the transport. The default implementation does nothing, a subclass can override it if it needs to take action when the message is successfully sent.

Parameters:
