Base class for searching for global kernel objects.

This is the base class for a number of classes which are used to find specific types of global kernel object such as semaphores, threads and mutexes; TFindSemaphore, TFindThread and TFindMutex are typical examples of such derived classes.

The class implements the common behaviour, specifically, the storage of the match pattern which is used to search for object names.

This class is not intended to be explicitly instantiated; it has public constructors but they are part of the class implementation and are described for information only.
