Detailed Description

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.

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.

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.

Return 0 if no consumer is connected...

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.
