Detailed Description


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.

void TAO_CEC_ProxyPushSupplier::_add_ref ( void  )
CORBA::ULong TAO_CEC_ProxyPushSupplier::_decr_refcnt ( void  )
PortableServer::POA_ptr TAO_CEC_ProxyPushSupplier::_default_POA ( void  )
CORBA::ULong TAO_CEC_ProxyPushSupplier::_incr_refcnt ( void  )

Increment and decrement the reference count.

void TAO_CEC_ProxyPushSupplier::_remove_ref ( void  )
void TAO_CEC_ProxyPushSupplier::activate ( CosEventChannelAdmin::ProxyPushSupplier_ptr &  activated_proxy)

Activate in the POA.

CosEventComm::PushConsumer_ptr TAO_CEC_ProxyPushSupplier::apply_policy ( CosEventComm::PushConsumer_ptr  c)

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

CORBA::Object_ptr TAO_CEC_ProxyPushSupplier::apply_policy_obj ( CORBA::Object_ptr  c)
void TAO_CEC_ProxyPushSupplier::cleanup_i ( void  )

Release the child and the consumer.

void TAO_CEC_ProxyPushSupplier::connect_push_consumer ( CosEventComm::PushConsumer_ptr  push_consumer)
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.

void TAO_CEC_ProxyPushSupplier::consumer ( CosEventComm::PushConsumer_ptr  consumer)

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

void TAO_CEC_ProxyPushSupplier::consumer_i ( CosEventComm::PushConsumer_ptr  consumer)
CORBA::Boolean TAO_CEC_ProxyPushSupplier::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_ProxyPushSupplier::deactivate ( void  )

Deactivate from the POA.

void TAO_CEC_ProxyPushSupplier::disconnect_push_supplier ( void  )
CORBA::Boolean TAO_CEC_ProxyPushSupplier::is_connected ( void  ) const

Return 0 if no consumer is connected...

CORBA::Boolean TAO_CEC_ProxyPushSupplier::is_connected_i ( void  ) const

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

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

Internal methods to push an event to each consumer.

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

Internal methods to invoke a typed event to each consumer.

Pushes to the consumer, verifies that it is connected.

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

The event channel is shutting down.

Member Data Documentation

CosEventComm::PushConsumer_var TAO_CEC_ProxyPushSupplier::consumer_

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

PortableServer::POA_var TAO_CEC_ProxyPushSupplier::default_POA_

Store the default POA.

TAO_CEC_EventChannel* TAO_CEC_ProxyPushSupplier::event_channel_

The Event Channel that owns this object.

ACE_Lock* TAO_CEC_ProxyPushSupplier::lock_

The Typed Event Channel that owns this object.

The locking strategy.

CosEventComm::PushConsumer_var TAO_CEC_ProxyPushSupplier::nopolicy_consumer_

The consumer without any policies applied.

CORBA::ULong TAO_CEC_ProxyPushSupplier::refcount_

The reference count.
