Description

RWTWriteLockGuardBase<Resource> is intended as a base class for guard classes that acquire write access on a resource upon creation and release it upon destruction. Guard objects work in conjunction with block statements in such a way as to establish an appropriate state upon creation, maintain that state for the duration of the block, and restore the original state upon destruction. For example, a guard may acquire write access on a mutex upon creation and release it when destructed. The class used as the actual template parameter for Resource must be one that provides acquireWrite and release methods (such as the synchronization classes provided in this module).

Public Typedef

typedef Resource     ResourceType;

Public Destructor

~RWTWriteLockGuardBase();

Releases the resource if it has been acquired.

Protected Constructor

RWTWriteLockGuardBase(Resource& resource);

Constructs an instance with the given resource. Note that this constructor does not attempt to acquire write access on the resource. That is the responsibility of the derived class.

Private Constructor

RWTWriteLockGuardBase(const RWTWriteLockGuardBase<Resource>&
                       second);

Copy construction prohibited.

Private Member Operator

RWTWriteLockGuardBase<Resource>&
operator=(const RWTWriteLockGuardBase<Resource>&
                       second);

Assignment prohibited.
