Class TFindLogicalDevice

class TFindLogicalDevice : public TFindHandleBase;

Description

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

An LDD factory object is an instance of a DLogicalDevice 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 TFindLogicalDevice::Next() repeatedly to find successive LDD factory objects whose names match the current pattern. A successful call to TFindLogicalDevice::Next() means that a matching LDD factory object has been found.

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