Member Function Documentation

int TAO_Notify_Buffering_Strategy::dequeue (  TAO_Notify_Method_Request_Queueable *&  method_request, const ACE_Time_Value *  abstime )

Dequeue batch. This method will block for abstime if non-zero or else blocks till an item is available. Return -1 on error or if nothing is available, else the number of items actually dequeued (1).

bool TAO_Notify_Buffering_Strategy::discard (  TAO_Notify_Method_Request_Queueable &  method_request  )  [private]

Discard as per the Discard Policy.

int TAO_Notify_Buffering_Strategy::enqueue (  TAO_Notify_Method_Request_Queueable &  method_request  )

Enqueue according the enqueing strategy. Return -1 on error else the number of items in the queue.

int TAO_Notify_Buffering_Strategy::queue (  TAO_Notify_Method_Request_Queueable &  method_request  )  [private]

Apply the Order Policy and queue. return -1 on error.

void TAO_Notify_Buffering_Strategy::shutdown (  void   )

Shutdown.

void TAO_Notify_Buffering_Strategy::update_qos_properties (  const TAO_Notify_QoSProperties &  qos_properties  )

Update state with the following QoS Properties: Order Policy Discard Policy MaxEventsPerConsumer TAO_Notify_Extensions::BlockingPolicy
