Description

  TA* a1 = new TA;
  TInstanceOf<TA> a2 (a1);

TInstanceOf(const TInstanceOf& copy) -- copies the object pointed to by the given TInstanceOf (if any), and adopts the copy.

~TInstanceOf() -- destroys the object being pointed to (if any).

operator=(AType* adopt) -- adopts the given object, and destroys the object (if any) to which this wrapper pointed previously. The new object (if any) is not copied.

operator=(const TInstanceOf& rhs) -- copies the object pointed to by the given TInstanceOf (if any), adopts the copy, and destroys the object (if any) to which this wrapper pointed previously.

Orphan() -- returns a copy of the pointer, and releases the management of it. GetAlias() will subsequently return NIL.

operator ==(), operator !=() -- compare the pointers for equality. operator == returns kTrue if they point to the same object, or if they are both NIL; otherwise it returns kFalse. operator != is the Boolean negation of operator ==.

Resurrect (TInstanceOf<AType>&, TStream& from,...) -- resurrects an object from a stream, and assigns a pointer to the resurrected object into the wrapper. This function won't compile unless Resurrect(AType*&, TStream&) is available.

TInstanceOf also inherits the interface and implementation of TPointerTo.
