This class implements support for a reference counted auto_ptr. Assigning or copying instances of an ACE_Refcounted_Auto_Ptr will automatically increment the reference count. When the last instance that references a ACE_Refcounted_Auto_Ptr instance is destroyed or overwritten, it will invoke delete on its underlying pointer.

Detailed Description
template<class X, class ACE_LOCK>
class ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >
This class implements support for a reference counted auto_ptr. Assigning or copying instances of an ACE_Refcounted_Auto_Ptr will automatically increment the reference count. When the last instance that references a ACE_Refcounted_Auto_Ptr instance is destroyed or overwritten, it will invoke delete on its underlying pointer.
The ACE_Refcounted_Auto_Ptr works by maintaining a reference to a separate representation object, ACE_Refcounted_Auto_Ptr_Rep. That separate representation object contains the reference count and the actual pointer value.

template<class X , class ACE_LOCK >
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.

template<class X , class ACE_LOCK >
Get the reference count value.
template<class X , class ACE_LOCK >
template<class X , class ACE_LOCK >
Returns true if this object does not contain a valid pointer.
template<class X , class ACE_LOCK >
template<class X , class ACE_LOCK >
template<class X, class ACE_LOCK>
Inequality operator, which is the opposite of equality.
template<class X , class ACE_LOCK >
template<class X , class ACE_LOCK >
template<class X, class ACE_LOCK>
template<class X, class ACE_LOCK>
Equality operator that returns true if both ACE_Refcounted_Auto_Ptr objects point to the same underlying representation. It does not compare the actual pointers.
- Note
- It also returns
true if both objects have just been instantiated and not used yet.
template<class X , class ACE_LOCK >
Releases the reference to the underlying representation object.
- Return values
-
| The | pointer value prior to releasing it. |
template<class X, class ACE_LOCK >
Releases the current pointer value and then sets a new pointer value specified by p.
