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. More...

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.

inlineexplicit |
Constructor that initializes an ACE_Refcounted_Auto_Ptr to the specified pointer value.
|
inline |
Copy constructor binds the new ACE_Refcounted_Auto_Ptr to the representation object referenced by r. An ACE_Refcounted_Auto_Ptr_Rep is created if necessary.
|
virtual |
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.

inline |
Get the reference count value.
|
inline |
Get the pointer value.

Returns true
if this object does not contain a valid pointer.

Accessor method.

Redirection operator.
|
inline |
Assignment operator that binds the current object and r to the same ACE_Refcounted_Auto_Ptr_Rep. An ACE_Refcounted_Auto_Ptr_Rep is created if necessary.
|
inline |
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.
true
if both objects have just been instantiated and not used yet.
|
inline |
Releases the reference to the underlying representation object.

|
inline |
Releases the current pointer value and then sets a new pointer value specified by p.
