Detailed Description

Same as to the ACE_Condition variable wrapper.

This class differs from ACE_Condition in that it uses a TAO_SYNCH_CONDITION instead of ACE_cond_t under the hood to provide blocking.

Member Typedef Documentation

typedef MUTEX TAO_Condition::LOCK

Useful typedef.

Constructor & Destructor Documentation

TAO_Condition::TAO_Condition ( MUTEX & m )

Initialize the condition variable.

TAO_Condition::TAO_Condition ( void )

A default constructor. Since no lock is provided by the user, one will be created internally.

TAO_Condition::~TAO_Condition ( void )

Implicitly destroy the condition variable.

Member Function Documentation

int TAO_Condition::broadcast ( void )

Signal *all* waiting threads.

MUTEX * TAO_Condition::mutex ( void )

Returns a reference to the underlying mutex_;.

int TAO_Condition::remove ( void )

Explicitly destroy the condition variable.

int TAO_Condition::signal ( void )

Signal one waiting thread.

int TAO_Condition::wait ( const ACE_Time_Value * abstime )

Block on condition, or until absolute time-of-day has passed. If abstime == 0 use "blocking" <wait> semantics. Else, if <abstime> != 0 and the call times out before the condition is signaled <wait> returns -1 and sets errno to ETIME.

int TAO_Condition::wait ( void )

Block on condition.

int TAO_Condition::wait	(	MUTEX &	mutex,
		const ACE_Time_Value *	abstime = `0`
	)

Block on condition or until absolute time-of-day has passed. If abstime == 0 use "blocking" wait() semantics on the <mutex> passed as a parameter (this is useful if you need to store the <Condition> in shared memory). Else, if <abstime> != 0 and the call times out before the condition is signaled <wait> returns -1 and sets errno to ETIME.

TAO_SYNCH_CONDITION* TAO_Condition::cond_ [private]

Condition variable.

bool TAO_Condition::delete_lock_ [private]

A flag to indicate whether the lock needs to be deleted.

MUTEX* TAO_Condition::mutex_ [private]

Reference to mutex lock.
