Member Function Documentation

◆ Apply()

template<typename MutexT , typename RecurseCountsT >
void ROOT::TRWMutexImp< MutexT, RecurseCountsT >::Apply ( std::unique_ptr< StateDelta > &&  delta)
overridevirtual

Apply the mutex state delta.

In pseudo-code: current_lock_count += delta;

Implements ROOT::TVirtualRWMutex.

Definition at line 95 of file TRWMutexImp.cxx.

◆ Factory()

template<typename MutexT , typename RecurseCountsT >
TVirtualRWMutex * ROOT::TRWMutexImp< MutexT, RecurseCountsT >::Factory ( Bool_t  = kFALSE)
overridevirtual

Create mutex and return pointer to it.

Implements ROOT::TVirtualRWMutex.

Definition at line 67 of file TRWMutexImp.cxx.

◆ GetStateBefore()

template<typename MutexT , typename RecurseCountsT >
std::unique_ptr< TVirtualRWMutex::State > ROOT::TRWMutexImp< MutexT, RecurseCountsT >::GetStateBefore
overridevirtual

Get the mutex state before the current lock was taken.

This function must only be called while the mutex is locked.

Implements ROOT::TVirtualRWMutex.

Definition at line 106 of file TRWMutexImp.cxx.

◆ ReadLock()

template<typename MutexT , typename RecurseCountsT >
TVirtualRWMutex::Hint_t * ROOT::TRWMutexImp< MutexT, RecurseCountsT >::ReadLock
overridevirtual

Take the Read Lock of the mutex.

Implements ROOT::TVirtualRWMutex.

Definition at line 31 of file TRWMutexImp.cxx.

◆ ReadUnLock()

template<typename MutexT , typename RecurseCountsT = ROOT::Internal::RecurseCounts>
void ROOT::TRWMutexImp< MutexT, RecurseCountsT >::ReadUnLock ( Hint_t *  )
overridevirtual

Release the read lock of the mutex.

Implements ROOT::TVirtualRWMutex.

Definition at line 49 of file TRWMutexImp.cxx.

◆ Rewind()

template<typename MutexT , typename RecurseCountsT >
std::unique_ptr< TVirtualRWMutex::StateDelta > ROOT::TRWMutexImp< MutexT, RecurseCountsT >::Rewind ( const State &  earlierState)
overridevirtual

Restore the mutex state to state.

This function must only be called while the mutex is locked. Returns the DeltaState between now and the resulting state (i.e. lock count before state), such that the difference can be re-applied using Apply(). In pseudo-code: delta = current_lock_count - earlierState.lock_count; current_lock_count -= delta; return delta;

Implements ROOT::TVirtualRWMutex.

Definition at line 84 of file TRWMutexImp.cxx.

◆ WriteLock()

template<typename MutexT , typename RecurseCountsT >
TVirtualRWMutex::Hint_t * ROOT::TRWMutexImp< MutexT, RecurseCountsT >::WriteLock
overridevirtual

Take the Write Lock of the mutex.

Implements ROOT::TVirtualRWMutex.

Definition at line 40 of file TRWMutexImp.cxx.

◆ WriteUnLock()

template<typename MutexT , typename RecurseCountsT = ROOT::Internal::RecurseCounts>
void ROOT::TRWMutexImp< MutexT, RecurseCountsT >::WriteUnLock ( Hint_t *  )
overridevirtual

Release the read lock of the mutex.

Implements ROOT::TVirtualRWMutex.

Definition at line 58 of file TRWMutexImp.cxx.
