RWTReadLockGuard<Resource>RWTReadLockGuardBase<Resource>
#include <rw/sync/RWTReadLockGuard.h>
RWTReadLockGuard<Resource> is a guard class that acquires read access on its resource upon creation and releases 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 by the library).

// ...
RWReaderWritersLock rwlock;
void foo()
{
// acquire read access:
RWTReadLockGuard<RWReaderWritersLock> lock(rwlock);
// ... critical section
// lock will be released in RWTReadLockGuard destructor
// before leaving scope, especially important if an exception
// might be thrown!
}
typedef Resource ResourceType;
RWTReadLockGuard(Resource& resource);
Constructs an instance with the given resource and acquires read access on that resource. (The resource will be released in the destructor of the base class.)
RWTReadLockGuard(const RWTReadLockGuard<Resource>& second);
Copy constructor is protected to disallow copy construction.
RWTReadLockGuard<Resource>& operator=(const RWTReadLockGuard<Resource>& second);
Assignment operator is protected to disallow assignment.
