ProxyPullSupplier.
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.

virtual |
Activate in the POA.
|
protected |
Assigns the parameter to both consumer_ and nopolicy_consumer_, and applies policies (when appropriate) to consumer_.
|
protected |
Release the child and the consumer.
|
virtual |
| CosEventComm::PullConsumer_ptr TAO_CEC_ProxyPullSupplier::consumer | ( | void | ) | const |
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.
|
protected |
Set the consumer, used by some implementations to change the policies used when invoking operations on the consumer.
|
protected |
| CORBA::Boolean TAO_CEC_ProxyPullSupplier::consumer_non_existent | ( | CORBA::Boolean_out | disconnected | ) |
Invoke the _non_existent() pseudo-operation on the consumer. If it is disconnected then it returns true and sets the <disconnected> flag.
|
virtual |
Deactivate from the POA.
|
virtual |
| CORBA::Boolean TAO_CEC_ProxyPullSupplier::is_connected | ( | void | ) | const |
Return 0 if no consumer is connected...
|
protected |
The private version (without locking) of is_connected().
|
virtual |
| void TAO_CEC_ProxyPullSupplier::push | ( | const CORBA::Any & | event | ) |
Push an event into the queue.
|
virtual |
The event channel is shutting down.
|
virtual |
|
private |
If the flag is not zero then we are connected, notice that the consumer can be nil.
|
private |
The consumer – use apply_policy() instead of assigning directly to consumer_. This will keep consumer_ and nopolicy_consumer_ in sync.
|
private |
Store the default POA.
|
private |
The Event Channel that owns this object.
|
private |
