public class QTPointerRef
extends QTObject
implements QuickTimeLib
A QTPointerRef is a "smart" pointer in that it can be either a Reference to a pointer which is not disposable, or it can be a real "independent" pointer which is automatically disposed on finalization.
The default setting is for the Ptr to be disposable - you must use the QTPointerRef(int, int, Object) constructor to create a non-disposable reference For non-disposable Pointers there are two situations to look out for:
(1) Upon finalization the pointer should NOT be disposed - it belongs to a parent struct
(2) The parent object from which the pointer is obtained should not be allowed to go away whilst the reference object is alive.
In both situations we must maintain a reference to the parent or owner object.
