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_CEC_MT_Dispatching::activate ( void  )

virtual

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

Implements TAO_CEC_Dispatching.

void TAO_CEC_MT_Dispatching::push ( TAO_CEC_ProxyPushSupplier *  proxy, const CORBA::Any &  event  )

virtual

The consumer represented by <proxy> should receive <event>.

Implements TAO_CEC_Dispatching.

void TAO_CEC_MT_Dispatching::push_nocopy ( TAO_CEC_ProxyPushSupplier *  proxy, CORBA::Any &  event  )

virtual

Implements TAO_CEC_Dispatching.

void TAO_CEC_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_CEC_Dispatching.

Member Data Documentation

int TAO_CEC_MT_Dispatching::active_

private

Are the threads running?

int TAO_CEC_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_CEC_MT_Dispatching::lock_

private

Synchronize access to internal data.

int TAO_CEC_MT_Dispatching::nthreads_

private

The number of active tasks.

private

The dispatching task.

int TAO_CEC_MT_Dispatching::thread_creation_flags_

private

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

ACE_Thread_Manager TAO_CEC_MT_Dispatching::thread_manager_

private

Use our own thread manager.

int TAO_CEC_MT_Dispatching::thread_priority_

private

The priority of the dispatching threads.
