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  )

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 

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 

Implements TAO_CEC_Dispatching.

void TAO_CEC_MT_Dispatching::shutdown ( void  )

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_

Are the threads running?

int TAO_CEC_MT_Dispatching::force_activate_

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

TAO_SYNCH_MUTEX TAO_CEC_MT_Dispatching::lock_

Synchronize access to internal data.

int TAO_CEC_MT_Dispatching::nthreads_

The number of active tasks.

TAO_CEC_Dispatching_Task TAO_CEC_MT_Dispatching::task_

The dispatching task.

int TAO_CEC_MT_Dispatching::thread_creation_flags_

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

ACE_Thread_Manager TAO_CEC_MT_Dispatching::thread_manager_

Use our own thread manager.

int TAO_CEC_MT_Dispatching::thread_priority_

The priority of the dispatching threads.
