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.

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.
