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.

Member Data Documentation

int TAO_EC_MT_Dispatching::active_ [private]

Are the threads running?

int TAO_EC_MT_Dispatching::force_activate_ [private]

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

TAO_SYNCH_MUTEX TAO_EC_MT_Dispatching::lock_ [private]

Synchronize access to internal data.

int TAO_EC_MT_Dispatching::nthreads_ [private]

The number of active tasks.

TAO_EC_Dispatching_Task TAO_EC_MT_Dispatching::task_ [private]

The dispatching task.

int TAO_EC_MT_Dispatching::thread_creation_flags_ [private]

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

ACE_Thread_Manager TAO_EC_MT_Dispatching::thread_manager_ [private]

Use our own thread manager.

int TAO_EC_MT_Dispatching::thread_priority_ [private]

The priority of the dispatching threads.
