How to add message filter on broker server side

[Jiang <zj...@163.com>]

I create on destination on the broker server and register several consumers
and producers(use topic). Default , all the consumers will receive the
messages from producers(On client side , we can add message filter to do
some selection). But I think that we can add some filters on the server
side, then the broker will not dispatch so much messages to all consumer
(for example , A sends message to B , default C will also receives the
message , but if I add client_id = B in the message header or other places,
broker can read this from the message , then broker will just send this
message to B). What I think is correct ? How can I modify the source code to
meet the request or How to use current code to realize the need. Any help is
welcome.

FWIW the broker implements selectors on the broker side

Just use JMS selectors and the broker implements them on the server;
no messages are dispatched to topic consumers unless they match the
topic and selector
