This class implements support for a reference counted auto_ptr. It assumes reference counting abilities of the parameterizing class.
Assigning or copying instances of an ACE_Intrusive_Auto_Ptr will automatically increment the reference count. When the last instance that references a ACE_Intrusive_Auto_Ptr instance is destroyed or overwritten, it will invoke delete on its underlying pointer.
The ACE_Intrusive_Auto_Ptr works by maintaining a reference to a separate representation object, ACE_Intrusive_Auto_Ptr_Rep. That separate representation object contains the reference count and the actual pointer value.

ACE_Intrusive_Auto_Ptr< X >::ACE_Intrusive_Auto_Ptr | ( | const ACE_Intrusive_Auto_Ptr< X > & | r | ) | [inline] |
Copy constructor binds the new ACE_Intrusive_Auto_Ptr to the representation object referenced by r. An ACE_Intrusive_Auto_Ptr_Rep is created if necessary.

Destructor. Releases the reference to the underlying representation. If the release of that reference causes its reference count to reach 0, the representation object will also be destroyed.
