Detailed Description


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.

Member Function Documentation

void TAO_CEC_ProxyPullSupplier::activate ( CosEventChannelAdmin::ProxyPullSupplier_ptr &  activated_proxy  )  [virtual]

Activate in the POA.

void TAO_CEC_ProxyPullSupplier::deactivate ( void   )  [virtual]

Deactivate from the POA.

ACE_INLINE CORBA::Boolean TAO_CEC_ProxyPullSupplier::is_connected ( void   )  const

Return 0 if no consumer is connected...

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.

void TAO_CEC_ProxyPullSupplier::shutdown ( void   )  [virtual]

The event channel is shutting down.

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.

void TAO_CEC_ProxyPullSupplier::push ( const CORBA::Any &  event  ) 

Push an event into the queue.

void TAO_CEC_ProxyPullSupplier::connect_pull_consumer ( CosEventComm::PullConsumer_ptr  pull_consumer  )  [virtual]

CORBA::Any * TAO_CEC_ProxyPullSupplier::pull ( void   )  [virtual]

CORBA::Any * TAO_CEC_ProxyPullSupplier::try_pull ( CORBA::Boolean_out  has_event  )  [virtual]

void TAO_CEC_ProxyPullSupplier::disconnect_pull_supplier ( void   )  [virtual]

CORBA::ULong TAO_CEC_ProxyPullSupplier::_incr_refcnt ( void   ) 

Increment and decrement the reference count.

CORBA::ULong TAO_CEC_ProxyPullSupplier::_decr_refcnt ( void   ) 

PortableServer::POA_ptr TAO_CEC_ProxyPullSupplier::_default_POA ( void   )  [virtual]

void TAO_CEC_ProxyPullSupplier::_add_ref ( void   )  [virtual]

void TAO_CEC_ProxyPullSupplier::_remove_ref ( void   )  [virtual]

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 void TAO_CEC_ProxyPullSupplier::consumer_i ( CosEventComm::PullConsumer_ptr  consumer  )  [protected]

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::cleanup_i ( void   )  [protected]

Release the child and the consumer.

CosEventComm::PullConsumer_ptr TAO_CEC_ProxyPullSupplier::apply_policy ( CosEventComm::PullConsumer_ptr  c  )  [protected]

Assigns the parameter to both consumer_ and nopolicy_consumer_, and applies policies (when appropriate) to consumer_.

Member Data Documentation

The Event Channel that owns this object.

The locking strategy.

The reference count.

CosEventComm::PullConsumer_var TAO_CEC_ProxyPullSupplier::consumer_ [private]

The consumer -- use apply_policy() instead of assigning directly to consumer_. This will keep consumer_ and nopolicy_consumer_ in sync.

CosEventComm::PullConsumer_var TAO_CEC_ProxyPullSupplier::nopolicy_consumer_ [private]

The consumer without any policies applied.

If the flag is not zero then we are connected, notice that the consumer can be nil.

Store the default POA.

TAO_SYNCH_MUTEX TAO_CEC_ProxyPullSupplier::queue_lock_ [private]

Use a message queue to pass the.
