		CORBA::ULong	id,
		CORBA::Short	lane_priority,
		CORBA::ULong	static_threads,

Constructor.

TAO_Thread_Lane::~TAO_Thread_Lane ( void )

Destructor.

Member Function Documentation

int TAO_Thread_Lane::create_dynamic_threads ( CORBA::ULong number_of_threads ) [private]

Create number_of_threads of dynamic threads. Can be called multiple times.

int TAO_Thread_Lane::create_static_threads ( void )

Create the static threads - only called once.

int TAO_Thread_Lane::create_threads_i	(	TAO_Thread_Pool_Threads &	thread_pool,
		CORBA::ULong	number_of_threads,
		long	thread_flags
	)			`[private]`

CORBA::ULong TAO_Thread_Lane::current_threads ( void ) const

ACE_INLINE ACE_Time_Value const & TAO_Thread_Lane::dynamic_thread_idle_timeout ( void ) const

ACE_INLINE CORBA::ULong TAO_Thread_Lane::dynamic_threads ( void ) const

void TAO_Thread_Lane::finalize ( void )

Finalize the resources.

ACE_INLINE CORBA::ULong TAO_Thread_Lane::id ( void ) const

int TAO_Thread_Lane::is_collocated ( const TAO_MProfile & mprofile )

Does mprofile belong to us?

ACE_INLINE CORBA::Short TAO_Thread_Lane::lane_priority ( void ) const

ACE_INLINE CORBA::Short TAO_Thread_Lane::native_priority ( void ) const

bool TAO_Thread_Lane::new_dynamic_thread ( void )

It can be that no thread can be created because the number of threads is equal to the maximum we can have or the Thread Lane is shutting down.

Return values:

	true	A new thread is created
	false	No thread could be created

void TAO_Thread_Lane::open ( void )

Open the lane.

ACE_INLINE TAO_Thread_Pool & TAO_Thread_Lane::pool ( void ) const

ACE_INLINE TAO_Thread_Lane_Resources & TAO_Thread_Lane::resources ( void )

void TAO_Thread_Lane::shutdown_reactor ( void )

Shutdown the reactor.

void TAO_Thread_Lane::shutting_down ( void )

Mark that this lane is shutting down, we then don't create any dynamic threads anymore. When the pool is shutting down the leader follower loop is called which can cause a request to create a new dynamic thread but we shouldn't create a new one.
