Description:This is an abstract class for device handles which are responsible for finalization i.e. to destroy underlying system resources, when the GC frees an object which has created some system object. Currently, these are forms and views (streams, cursors, colors and fonts could also make use of this class - however, for historical reasons, they continue to use their own private finalization machanisms. This may change in future versions). Related information:DeviceDrawable Class protocol:queries
