virtual void readLock (   )  [virtual]

Obtain a read lock on the mutex object. Multiple readers may concurrently hold a read lock but not at the same time as a writer.

virtual void unlock (   )  [virtual]

Unlock the mutex object. It doesn't matter if the mutex was previously read or write locked. Implements MCMutex.

virtual void writeLock (   )  [virtual]

Obtain a write lock on the mutex object. A single writer may hold a read lock but not at the same time as other writers or readers.
