Detailed Description

template<class MUTEX>
class TAO_Condition< MUTEX >

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

template<class MUTEX >
typedef MUTEX TAO_Condition< MUTEX >::LOCK

Useful typedef.


Constructor & Destructor Documentation

template<class MUTEX >
TAO_Condition< MUTEX >::TAO_Condition ( MUTEX &  m)

Initialize the condition variable.

template<class MUTEX >
TAO_Condition< MUTEX >::TAO_Condition ( void  )

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

template<class MUTEX >
TAO_Condition< MUTEX >::~TAO_Condition ( void  )

Implicitly destroy the condition variable.


Member Function Documentation

template<class MUTEX >
int TAO_Condition< MUTEX >::broadcast ( void  )

Signal *all* waiting threads.

template<class MUTEX >
MUTEX * TAO_Condition< MUTEX >::mutex ( void  )

Returns a reference to the underlying mutex_;.

template<class MUTEX >
int TAO_Condition< MUTEX >::remove ( void  )

Explicitly destroy the condition variable.

template<class MUTEX >
int TAO_Condition< MUTEX >::signal ( void  )

Signal one waiting thread.

template<class MUTEX >
int TAO_Condition< MUTEX >::wait ( void  )

Block on condition.

template<class MUTEX >
int TAO_Condition< MUTEX >::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.

template<class MUTEX >
int TAO_Condition< MUTEX >::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.


Member Data Documentation

template<class MUTEX >
TAO_SYNCH_CONDITION* TAO_Condition< MUTEX >::cond_ [private]

Condition variable.

template<class MUTEX >
bool TAO_Condition< MUTEX >::delete_lock_ [private]

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

template<class MUTEX >
MUTEX* TAO_Condition< MUTEX >::mutex_ [private]

Reference to mutex lock.
