Subject svn commit: r1160807 - in /activemq/activemq-apollo/trunk: apollo-dto/src/main/java/org/apache/activemq/apollo/dto/ apollo-web/src/main/scala/org/apache/activemq/apollo/web/resources/

New Revision: 1160807

URL: http://svn.apache.org/viewvc?rev=1160807&view=rev
Log:
- Expose the current time in the queue-metrics
- Add topic, queue, dsub  count fields in the virtual_host_status so that the aggregate count
can more easily be obtained via the tabular management interface.
- The virtual host collection is now exposed as a tabular view too.
- The tabular view now can display fields which only exist in subclasses of the objects.
