Subject svn commit: r518961 - in /activemq/activemq-cpp/trunk/activemq-cpp/src/main/activemq: connector/ connector/openwire/ connector/stomp/ core/
Date Fri, 16 Mar 2007 12:59:37 GMT
Author: tabish
Date: Fri Mar 16 05:59:36 2007
New Revision: 518961

URL: http://svn.apache.org/viewvc?view=rev&rev=518961
Log:
http://issues.apache.org/activemq/browse/AMQCPP-81

Changed the Connector interface so that when a consumer is created, two methods are called.
 

createConsumer which sets up the consumer and returns a valid ConsumerInfo pointer.
startConsumer which actually registers the consumer with the broker.

This allows the consumer to be prepared but not actually started until the managing class
is setup and ready for messages.
