RWTTryReadLockGuard is a guard class that tries to acquire read 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 read 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 tryAcquireRead
() and release
() methods, such as some synchronization classes provided in this module.

Constructs an instance with the given resource and attempts to acquire read access on that resource. Uses the inherited isAcquired() member function to see if the acquisition was successful.

Tries again to acquire read access on the resource. Use this function instead of manipulating the resource directly so the guard will automatically release it.
