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.

Constructor & Destructor Documentation

template<class X, class ACE_LOCK>

ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::ACE_Refcounted_Auto_Ptr

(

X *

p = 0

)

[inline, explicit]

Constructor that initializes an ACE_Refcounted_Auto_Ptr to the specified pointer value.

template<class X, class ACE_LOCK>

ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::ACE_Refcounted_Auto_Ptr

(

const ACE_Refcounted_Auto_Ptr< X, ACE_LOCK > &

r

)

[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.

template<class X, class ACE_LOCK>

ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::~ACE_Refcounted_Auto_Ptr

(

void

)

[inline, 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.

Member Function Documentation

template<class X, class ACE_LOCK>

void ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::operator=

(

const ACE_Refcounted_Auto_Ptr< X, ACE_LOCK > &

r

)

[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.

template<class X, class ACE_LOCK>

bool ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::operator==

(

const ACE_Refcounted_Auto_Ptr< X, ACE_LOCK > &

r

)

const [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.

Note:

It also returns true if both objects have just been instantiated and not used yet.

template<class X, class ACE_LOCK>

bool ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::operator!=

(

const ACE_Refcounted_Auto_Ptr< X, ACE_LOCK > &

r

)

const [inline]

Inequality operator, which is the opposite of equality.

template<class X, class ACE_LOCK>

X * ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::operator->

(

void

)

const [inline]

Redirection operator.

template<class X, class ACE_LOCK>

X & ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::operator*

(

)

const [inline]

Accessor method.

template<class X, class ACE_LOCK>

bool ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::operator!

(

)

const [inline]

Check rep easily.

const [inline]

Check rep easily.

template<class X, class ACE_LOCK>

X * ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::release

(

void

)

[inline]

Releases the reference to the underlying representation object.

Return values:

The

pointer value prior to releasing it.

template<class X, class ACE_LOCK>

void ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::reset

(

X *

p = 0

)

[inline]

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

template<class X, class ACE_LOCK>

X * ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::get

(

void

)

const [inline]

Get the pointer value.

template<class X, class ACE_LOCK>

long ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::count

(

void

)

const [inline]

Get the reference count value.

template<class X, class ACE_LOCK>

bool ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::null

(

void

)

const [inline]

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