Method Detail

sendEvent

public void sendEvent(JavaSpace source,
             long now,
             ProxyPreparer preparer)
               throws UnknownEventException,
                      IOException,
                      ClassNotFoundException

Description copied from interface: EventSender

Send a remote event to the encapsulated listener of the encapsulated type, with the encapsulated handback, sequence number. No locks should be held while calling the listener. This method may be called more than once if all previous tries failed. This call may do nothing and return normally if it is determined that delivering the event is no longer useful. It is assumed that once this method returns normally it will not be called again.

Specified by:

sendEvent in interface EventSender

Parameters:

source - the source the event object sent to the lister should have.

now - The current time.

preparer - to apply to the listener if it has been recovered from a store and not yet re-prepared in this VM.

Throws:

UnknownEventException - if the call to the listener does. Note, this will not cause the watcher to remove itself.

IOException - if the listener can not be unmarshalled. May throw RemoteException if the call to the listener or preparer does

ClassNotFoundException - if the listener needs to be unmarshalled and a necessary class can not be found.

cancelRegistration

public void cancelRegistration()

Description copied from interface: EventSender

Called when the event sending infrastructure decides to give up on the event registration associated with this sender.

Specified by:

cancelRegistration in interface EventSender

getOwner

private EventRegistrationWatcher getOwner()

Return the EventRegistrationWatcher this object is part of (exits because (BasicEventSender)other).EventRegistrationWatcher. this does not work.

runAfter

public boolean runAfter(EventSender other)

Run after another event sender if it is for the same registration. No sense sending the same event twice. Don't care which one goes first (though the second probably won't run since lastSeqNumDelivered will probably equal currentSeqNum when it runs).

Specified by:

runAfter in interface EventSender

Parameters:

other - the sender this object should compare itself too.

Returns:

true if this object should run after other.
