Detailed Description

Dispatching strategy that isolates deliveries to a consumer from any other.

This strategy uses a thread per consumer, and was specifically designed to isolate the effects of an ill-behaved consumer from affecting other consumers.

Member Function Documentation

void TAO_EC_TPC_Dispatching::activate ( void  ) [virtual]

Initialize all the data structures, activate any internal threads, etc.

Implements TAO_EC_Dispatching.

int TAO_EC_TPC_Dispatching::add_consumer ( RtecEventComm::PushConsumer_ptr  consumer)
void TAO_EC_TPC_Dispatching::push ( TAO_EC_ProxyPushSupplier proxy,
RtecEventComm::PushConsumer_ptr  consumer,
const RtecEventComm::EventSet event,
TAO_EC_QOS_Info qos_info 
) [virtual]

The consumer represented by proxy should receive event. It can use the information in qos_info to determine the event priority (among other things).

Implements TAO_EC_Dispatching.

void TAO_EC_TPC_Dispatching::push_nocopy ( TAO_EC_ProxyPushSupplier proxy,
RtecEventComm::PushConsumer_ptr  consumer,
RtecEventComm::EventSet event,
TAO_EC_QOS_Info qos_info 
) [virtual]

Implements TAO_EC_Dispatching.

int TAO_EC_TPC_Dispatching::remove_consumer ( RtecEventComm::PushConsumer_ptr  consumer)
void TAO_EC_TPC_Dispatching::shutdown ( void  ) [virtual]

Deactivate any internal threads and cleanup internal data structures, it should only return once the threads have finished their jobs.

Implements TAO_EC_Dispatching.


Member Data Documentation

If activation at the requested priority fails then we fallback on the defaults for thread activation.

The number of active tasks.

The flags (THR_BOUND, THR_NEW_LWP, etc.) used to create the dispatching threads.

The priority of the dispatching threads.
