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.

Increment and decrement the reference count.

Activate in the POA.
|
|
Release the child and the consumer.
|
|
|
|
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.
|
|
|
|
Return 0 if no consumer is connected...
|
|
The private version (without locking) of is_connected().
|
|
|
|
Push an event into the queue.
|
|
The event channel is shutting down.
|
|
|
|
If the flag is not zero then we are connected, notice that the consumer can be nil. |
