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.

private

int TAO_EC_TPC_Dispatching::thread_priority_

private

The priority of the dispatching threads.
