Detailed Description

template<class Resource>
class RWTLockGuardBase< Resource >

RWTLockGuardBase<Resource> is a base class for guard classes that acquire their resource upon creation and release it upon destruction. Guard objects work in conjunction with block statements 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 a mutex upon creation and release it when destructed. The class used as the actual template parameter for Resource must be one that provides acquire() and release() methods, such as the synchronization classes of the Threads Module.
