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.

| CORBA::ULong TAO_CEC_ProxyPullSupplier::_incr_refcnt | ( | void | ) |
Increment and decrement the reference count.

| void TAO_CEC_ProxyPullSupplier::activate | ( | CosEventChannelAdmin::ProxyPullSupplier_ptr &activated_proxy | ACE_ENV_ARG_DECL | ) | throw (CORBA::SystemException) [virtual] |
Activate in the POA.
| void TAO_CEC_ProxyPullSupplier::cleanup_i | ( | void | ) | [protected] |
Release the child and the consumer.

| ACE_INLINE void TAO_CEC_ProxyPullSupplier::consumer | ( | CosEventComm::PullConsumer_ptr | consumer | ) | [protected] |
Set the consumer, used by some implementations to change the policies used when invoking operations on the consumer.
| ACE_INLINE 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.
| ACE_INLINE void TAO_CEC_ProxyPullSupplier::consumer_i | ( | CosEventComm::PullConsumer_ptr | consumer | ) | [protected] |
| CORBA::Boolean TAO_CEC_ProxyPullSupplier::consumer_non_existent | ( | CORBA::Boolean_out disconnected | ACE_ENV_ARG_DECL | ) |
Invoke the _non_existent() pseudo-operation on the consumer. If it is disconnected then it returns true and sets the <disconnected> flag.
| void TAO_CEC_ProxyPullSupplier::deactivate | ( | ACE_ENV_SINGLE_ARG_DECL | ) | throw (CORBA::SystemException) [virtual] |
Deactivate from the POA.

| ACE_INLINE CORBA::Boolean TAO_CEC_ProxyPullSupplier::is_connected | ( | void | ) | const |
Return 0 if no consumer is connected...
| TAO_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE CORBA::Boolean TAO_CEC_ProxyPullSupplier::is_connected_i | ( | void | ) | const [protected] |
The private version (without locking) of is_connected().

| void TAO_CEC_ProxyPullSupplier::push | ( | const CORBA::Any &event | ACE_ENV_ARG_DECL | ) |
Push an event into the queue.
| void TAO_CEC_ProxyPullSupplier::shutdown | ( | ACE_ENV_SINGLE_ARG_DECL | ) | [virtual] |
The event channel is shutting down.

int TAO_CEC_ProxyPullSupplier::connected_ [private] |
If the flag is not zero then we are connected, notice that the consumer can be nil.
CosEventComm::PullConsumer_var TAO_CEC_ProxyPullSupplier::consumer_ [private] |
The consumer....
Store the default POA.
The Event Channel that owns this object.
ACE_Lock* TAO_CEC_ProxyPullSupplier::lock_ [private] |
The locking strategy.
