Detailed Description

ProxyPullConsumer.

Implement the CosEventChannelAdmin::ProxyPullConsumer interface, remember that this class is used to communicate with a PullSupplier, so, in effect, this is the ambassador for a supplier inside the event channel. = MEMORY MANAGMENT The object commits suicide when disconnect_pull_consumer() is called.

virtual void TAO_CEC_ProxyPullConsumer::_add_ref (   )  [virtual]

CORBA::ULong TAO_CEC_ProxyPullConsumer::_decr_refcnt (  void   )

CORBA::ULong TAO_CEC_ProxyPullConsumer::_incr_refcnt (  void   )

Increment and decrement the reference count.

virtual void TAO_CEC_ProxyPullConsumer::_remove_ref (   )  [virtual]

void TAO_CEC_ProxyPullConsumer::cleanup_i (  void   )  [protected]

Release the supplier.

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

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

CORBA::Any * TAO_CEC_ProxyPullConsumer::pull_from_supplier (   )

virtual void TAO_CEC_ProxyPullConsumer::shutdown (  ACE_ENV_SINGLE_ARG_DECL_NOT_USED   )  [virtual]

The event channel is shutting down.

ACE_INLINE void TAO_CEC_ProxyPullConsumer::supplier (  CosEventComm::PullSupplier_ptr  supplier  )  [protected]

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

ACE_INLINE CosEventComm::PullSupplier_ptr TAO_CEC_ProxyPullConsumer::supplier (  void   )  const

Return the consumer object reference. It returns nil() if it has not connected yet.

ACE_INLINE void TAO_CEC_ProxyPullConsumer::supplier_i (  CosEventComm::PullSupplier_ptr  supplier  )  [protected]

CORBA::Boolean TAO_CEC_ProxyPullConsumer::supplier_non_existent (  CORBA::Boolean_out  disconnected  )

Invoke the _non_existent() pseudo-operation on the supplier. If it is disconnected then it returns true and sets the <disconnected> flag.

CORBA::Any * TAO_CEC_ProxyPullConsumer::try_pull_from_supplier (  CORBA::Boolean_out  has_event  )

Pulls from the supplier, verifies that it is connected.
