## 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::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>
ACE_INLINE int TAO_Condition< MUTEX >::broadcast | ( | void |  | ) |

| Signal *all* waiting threads.

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

| Returns a reference to the underlying mutex_;.

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

| Explicitly destroy the condition variable.

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

| Signal one waiting thread.

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

| Block on condition.

template<class MUTEX>
ACE_INLINE 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.
