Detailed Description

ProxyPushSupplier.

Implement the CosEventChannelAdmin::ProxyPushSupplier interface, remember that this class is used to communicate with a PushConsumer, 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.

Member Function Documentation

void TAO_CEC_ProxyPushSupplier::_add_ref (  ACE_ENV_SINGLE_ARG_DECL   )  [virtual]

CORBA::ULong TAO_CEC_ProxyPushSupplier::_decr_refcnt (  void   )

PortableServer::POA_ptr TAO_CEC_ProxyPushSupplier::_default_POA (  ACE_ENV_SINGLE_ARG_DECL   )  [virtual]

void TAO_CEC_ProxyPushSupplier::_remove_ref (  ACE_ENV_SINGLE_ARG_DECL   )  [virtual]

void TAO_CEC_ProxyPushSupplier::cleanup_i (  void   )  [protected]

Release the child and the consumer.

ACE_INLINE void TAO_CEC_ProxyPushSupplier::consumer (  CosEventComm::PushConsumer_ptr  consumer  )  [protected]

Set the consumer, used by some implementations to change the policies used when invoking operations on the consumer.

ACE_INLINE CosEventComm::PushConsumer_ptr TAO_CEC_ProxyPushSupplier::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_ProxyPushSupplier::consumer_i (  CosEventComm::PushConsumer_ptr  consumer  )  [protected]

CORBA::Boolean TAO_CEC_ProxyPushSupplier::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.

ACE_INLINE CORBA::Boolean TAO_CEC_ProxyPushSupplier::is_connected_i (  void   )  const [protected]

The private version (without locking) of is_connected().

void TAO_CEC_ProxyPushSupplier::push (  const CORBA::Any &event  ACE_ENV_ARG_DECL  )  [virtual]

Internal methods to push an event to each consumer.

void TAO_CEC_ProxyPushSupplier::push_nocopy (  CORBA::Any &event  ACE_ENV_ARG_DECL  )  [virtual]

void TAO_CEC_ProxyPushSupplier::push_to_consumer (  const CORBA::Any &event  ACE_ENV_ARG_DECL  )

Pushes to the consumer, verifies that it is connected.

void TAO_CEC_ProxyPushSupplier::reactive_push_to_consumer (  const CORBA::Any &event  ACE_ENV_ARG_DECL  )

void TAO_CEC_ProxyPushSupplier::shutdown (  ACE_ENV_SINGLE_ARG_DECL   )  [virtual]

The event channel is shutting down.
