Detailed Description

Dispatching strategy that isolates deliveries to a consumer from any other.

This strategy uses a thread per consumer, and was specifically designed to isolate the effects of an ill-behaved consumer from affecting other consumers.

Member Function Documentation

void TAO_EC_TPC_Dispatching::activate

(

void

)

[virtual]

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

Implements TAO_EC_Dispatching.

int TAO_EC_TPC_Dispatching::add_consumer

(

RtecEventComm::PushConsumer_ptr

consumer

)

void TAO_EC_TPC_Dispatching::push	(	TAO_EC_ProxyPushSupplier *	proxy,
		RtecEventComm::PushConsumer_ptr	consumer,
		const RtecEventComm::EventSet &	event,
		TAO_EC_QOS_Info &	qos_info
	)			[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.

void TAO_EC_TPC_Dispatching::push_nocopy	(	TAO_EC_ProxyPushSupplier *	proxy,
		RtecEventComm::PushConsumer_ptr	consumer,
		RtecEventComm::EventSet &	event,
		TAO_EC_QOS_Info &	qos_info
	)			[virtual]

Implements TAO_EC_Dispatching.

int TAO_EC_TPC_Dispatching::remove_consumer

(

RtecEventComm::PushConsumer_ptr

consumer

)

void TAO_EC_TPC_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.

ACE_SYNCH_MUTEX TAO_EC_TPC_Dispatching::lock_ [private]

int TAO_EC_TPC_Dispatching::nthreads_ [private]

The number of active tasks.

int TAO_EC_TPC_Dispatching::thread_creation_flags_ [private]

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

ACE_Thread_Manager TAO_EC_TPC_Dispatching::thread_manager_ [private]

int TAO_EC_TPC_Dispatching::thread_priority_ [private]

The priority of the dispatching threads.
