template<class Resource>
class RWTTryWriteLockGuard< Resource >
RWTTryWriteLockGuard is a guard class that tries to acquire write access on its resource upon creation and, if successful, 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 write access on a mutex when created and release it when destructed. The class used as the actual template parameter for Resource
must be one that provides tryAcquireWrite
() and release
() methods, such as some synchronization classes provided in this module.
