Detailed Description

Dispatching strategy that minimizes mt inversion.

This strategy uses a single queue, serviced by one or more threads. It's main purpose is to decouple the suppliers from the client execution time, specially in the collocated case.

Member Function Documentation

void TAO_EC_MT_Dispatching::activate void   )  [virtual]
 

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

Implements TAO_EC_Dispatching.

void TAO_EC_MT_Dispatching::push TAO_EC_ProxyPushSupplier proxy,
RtecEventComm::PushConsumer_ptr  consumer,
const RtecEventComm::EventSet event,
TAO_EC_QOS_Info &qos_info  ACE_ENV_ARG_DECL
[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.

virtual void TAO_EC_MT_Dispatching::push_nocopy TAO_EC_ProxyPushSupplier proxy,
RtecEventComm::PushConsumer_ptr  consumer,
RtecEventComm::EventSet event,
TAO_EC_QOS_Info &qos_info  ACE_ENV_ARG_DECL
[virtual]
 

Implements TAO_EC_Dispatching.

void TAO_EC_MT_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.

Use our own thread manager.

int TAO_EC_MT_Dispatching::thread_priority_ [private]
