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.

| 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>.

| 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.
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.
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.
Use our own thread manager.
int TAO_CEC_MT_Dispatching::thread_priority_ [private] |
The priority of the dispatching threads.
