N.B. That the 0.12 C++ broker does not *actually* support subscriptions however it does periodically "push" QmfConsoleData Object updates as _data indications. The Console class uses these to provide client side emulation of broker subscriptions. One slightly subtle thing to bear in mind however is that the broker ManagementAgent separates "properties" and "statistics" so for example a subscription query on say a queue's name property will only evaluate true for a properties push and not a statistics push. The most useful usage pattern is likely to be a getObjects() call to return all queues, followed by a search for the queue of interest then a subscription with a query using the ObjectId of the wanted queue. @author Fraser Adams
