A Message-sent handler proposal [message #612045]

Hi,
working with ECF on my application, i need to handle send/receive messages of the shared objects for tracing all the messages that are received and sent from/to all the others shared objects; to handle received messages I can add a IEventProcessor, but I don't find any mechanism to handle the event that my shared object sent a message.
So, i've added this mechanism as an event/listener mechanism: i've a IMessageSendedHandler, and after the getContext().sendMessage(...), I fire the event to all registered listeners.

Can this problem be tackled (this way or any other) in one of the future releases of ECF?

thanks

It could. Just so I'm clear...you are interested in a listener for
*all* shared object messages within a given container?

Note another way to do what you want to do is to override one of the
container classes (TCPClientSOContainer) and override one of the
protected methods for handling shared object messages.

We could also build into the IContainerListener the notification of
shared object messages, and then any registered listeners (via
IContainer.addListener(IContainerListener) would be notified of these
messages (for ISharedObjectContainers anyway).

If you could describe the use case a little further we can jointly
figure out what the right answer is here.

Thanks,

Scott

i just catch all the message received events with a defaul event processor that record the events in a file, but also i want to catch all message sent by a shared object in a container (for tracing).

sorry for the delay of the reply :-)

thanks

Hi Antonio,

I think there are two ways to address this:

1) Extend the TCPClientSOContainer class (in org.eclipse.ecf.provider)
and override the method:

handleSharedObjectMessage

You can then intercept/record the shared object message to a file,
etc...and then call super.handleSharedObjectMessage(mess) to do the
regular processing.

2) I can add an enhancement that sends a sharedobjectmessage event (new
event type) to the IContainerListener for shared object containers.

Do people think that 2 is worth it? If so then I'll file an enhancement
request and I think I will be able to implement before 0.9.7 (Feb 15).

Hi,
i think that the second solution is better because for several reasons: it is more flexible for all shared object container types; if there are more processor for these events; in order to separate logic from the container implementation.

thanks :)

Hi Antonio,

Would you mind creating an enhancement request/bug for this?

https://bugs.eclipse.org/bugs/enter_bug.cgi?product=ECF

That way it will be tracked and interest from others can be recorded.

Thanks!
