public interface DestinationQueueMonitorService extends Service(Code)
This is an MTS-internal service, accessible only to child
components of the MTS, that allows those components to examine the
state of any given DestinationQueue. Implemented and provided by
DestinationQueueFactory.
Returns the current contents of a queue, as an array. The
in-progress message, if any, is included even though it's no
longer "on" the queue, strictlt speaking.
