>                 Key: QPID-693
>                 URL: https://issues.apache.org/jira/browse/QPID-693
>             Project: Qpid
>          Issue Type: Improvement
>          Components: C++ Broker
>            Reporter: Ted Ross
>            Priority: Minor
>         Attachments: qpid-patch10.diff
> Queue statistics fixed.  Additional objects added (exchange, binding).
> Changes:
> M      cpp/src/qpid/broker/ExchangeRegistry.h
> M      cpp/src/qpid/broker/ExchangeRegistry.cpp
>     ExchangeRegistry was modified to pass a parent pointer to created
>     exchanges.  This parent reference is not stored but is used to
>     link management objects in a hierarchy of ownership.
> M      cpp/src/qpid/broker/Exchange.h
> M      cpp/src/qpid/broker/Exchange.cpp
>     Exchange now inherits Manageable to make it visible via the
>     management interface.  The Exchange parent class handles most of
>     the management boilerplate.  A Binding struct was introduced to
>     track bindings for management.  This is separate from
>     QueueBindings which track bindings for queues.
> M      cpp/src/qpid/broker/HeadersExchange.h
> M      cpp/src/qpid/broker/FanOutExchange.h
> M      cpp/src/qpid/broker/DirectExchange.h
> M      cpp/src/qpid/broker/TopicExchange.h
> M      cpp/src/qpid/broker/HeadersExchange.cpp
> M      cpp/src/qpid/broker/FanOutExchange.cpp
> M      cpp/src/qpid/broker/DirectExchange.cpp
> M      cpp/src/qpid/broker/TopicExchange.cpp
> M      cpp/src/qpid/management/ManagementExchange.cpp
> M      cpp/src/qpid/management/ManagementExchange.h
>     Each exchange type handles management stats in its own specific
>     way.  Additionally, the constructors pass the management parent
>     pointer to the constructor or Exchange.
>     An extra layer was added to contain bindings.  Instead of directly
>     storing bound queues, the exchanges store "bindings" which are
>     managable constructs.
> M      cpp/src/qpid/broker/Broker.cpp
>     Broker now explicitly enables the management agent.  Also sets the
>     management parent (vhost) in the exchange registry.
> M      cpp/src/qpid/broker/Vhost.cpp
>     Updated constructor to be more defensive in case the management
>     agent has not been enabled.
> M      cpp/src/qpid/broker/Queue.cpp
>     Same constructor update as vhost.  Moved accounting of dequeues
>     into "pop". Implemented management method handler (purge).
> M      cpp/src/qpid/broker/Deliverable.h
>     A new method was added to extract the content size of the
>     deliverable content (if appropriate).  The method is not pure
>     virtual and returns zero if not overridden.
> M      cpp/src/qpid/broker/DeliverableMessage.h
> M      cpp/src/qpid/broker/TxPublish.cpp
> M      cpp/src/qpid/broker/DeliverableMessage.cpp
> M      cpp/src/qpid/broker/TxPublish.h
>     These derivatives of Deliverable were updated with overrides for
>     contenSize.
> M      cpp/src/qpid/management/ManagementAgent.h
> M      cpp/src/qpid/management/ManagementAgent.cpp
>     An "enable" method was added to prevent inadvertent creation of a
>     management agent when not desired.
>     Adding and deleting management objects is now protected by a
>     mutex.
>     Make sure that deleted objects get reported even if neither their
>     configuration nor instrumentation is changed.
> M      specs/management-schema.xml
>     Minor cosmetic updates.  Additional parent linkage.
> M      cpp/managementgen/schema.py
> M      cpp/managementgen/templates/Class.cpp
>     Added generated code to publish schema details for methods.
