svn commit: r541693 - in /activemq/camel/trunk: camel-core/
camel-core/src/main/java/org/apache/camel/
camel-core/src/main/java/org/apache/camel/builder/

Author: jstrachan
Date: Fri May 25 08:39:37 2007
New Revision: 541693
URL: http://svn.apache.org/viewvc?view=rev&rev=541693
Log:
added support for Rescheduler pattern to be able to reorder a message flow using an expression or pluggable comparator. It had a fairly big effect on the codebase as we had to support custom Route implementations (since a route might be just some Services which lazily create a PollingConsumer)
Added:
