Implement the CosEventChannelAdmin::ProxyPullSupplier interface, remember that this class is used to communicate with a PullConsumer, so, in effect, this is the ambassador for a consumer inside the event channel. = MEMORY MANAGMENT It does not assume ownership of the TAO_CEC_Dispatching object. It makes a copy of the ConsumerQOS and the consumer object reference. = LOCKING Locking is strategized, the event channel acts as a factory for the locking strategies.

|
|
Set the consumer, used by some implementations to change the policies used when invoking operations on the consumer.
|
|
Return the consumer object reference. It returns nil() if it has not connected yet. NOTE: This method does not return a new reference!!! Doing so will increase the locking overhead on the critical path. |
|
|
|
Invoke the _non_existent() pseudo-operation on the consumer. If it is disconnected then it returns true and sets the <disconnected> flag. |

Deactivate from the POA.
