Class TFindPhysicalDevice

class TFindPhysicalDevice : public TFindHandleBase;

Description

Searches for PDD factory objects by pattern matching against the names of PDD factory objects.

A PDD factory object is an instance of a DPhysicalDevice derived class.

The match pattern can be set into this object at construction; it can also be changed at any time after construction by using TFindHandleBase::Find().

After construction, call TFindPhysicalDevice::Next() repeatedly to find successive PDD factory objects whose names match the current pattern. A successful call to TFindPhysicalDevice::Next() means that a matching PDD factory object has been found.

The name of a PDD factory object is set by its Install() member function as part of the construction process.
