## 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.

| Constructor It will create nthreads servicing threads...

## 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.
