Description

RWTReadLockGuardBase<Resource> is intended as a base class for guard classes that acquire read 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 read 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 acquireRead and release methods, such as the synchronization classes provided in this module.

Public Destructor

~RWTReadLockGuardBase();

Releases the resource if it has been acquired.

Protected Constructor

RWTReadLockGuardBase(Resource& resource);

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

Private Constructor

RWTReadLockGuardBase(const 
                      RWTReadLockGuardBase<Resource>& second);

Dummy copy constructor required by derived class copy constructors. The copy constructor does not attempt to copy the resource.

Private Member Operator

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