Detailed Description

template<class X>
class ACE_Intrusive_Auto_Ptr< X >

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.

Constructor & Destructor Documentation

template<class X>

ACE_Intrusive_Auto_Ptr< X >::ACE_Intrusive_Auto_Ptr ( X *  p = 0, bool  addref = true  )

inline

Constructor that initializes an ACE_Intrusive_Auto_Ptr to the specified pointer value.

template<class X>

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.

template<class X >

template<class U >

ACE_Intrusive_Auto_Ptr< X >::ACE_Intrusive_Auto_Ptr ( const ACE_Intrusive_Auto_Ptr< U > &  rhs )

inline

template<class X >

ACE_Intrusive_Auto_Ptr< X >::~ACE_Intrusive_Auto_Ptr ( void  )

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>

long ACE_Intrusive_Auto_Ptr< X >::count

(

void

)

const

Get the reference count value.

template<class X >

X * ACE_Intrusive_Auto_Ptr< X >::get ( void  ) const

inline

Get the pointer value.

template<class X>

ACE_Intrusive_Auto_Ptr< X >::operator unspecified_bool_type ( ) const

inline

Enables "if (sp) ...".

template<class X >

X & ACE_Intrusive_Auto_Ptr< X >::operator* ( ) const

inline

Accessor method.

template<class X >

X * ACE_Intrusive_Auto_Ptr< X >::operator-> ( void  ) const

inline

Redirection operator.

template<class X>

void ACE_Intrusive_Auto_Ptr< X >::operator= ( const ACE_Intrusive_Auto_Ptr< X > &  r )

inline

Assignment operator that binds the current object and r to the same ACE_Intrusive_Auto_Ptr_Rep. An ACE_Intrusive_Auto_Ptr_Rep is created if necessary.

template<class X >

X * ACE_Intrusive_Auto_Ptr< X >::release ( void  )

inline

Releases the reference to the underlying representation object.

Return values

The	pointer value prior to releasing it.

template<class X>

void ACE_Intrusive_Auto_Ptr< X >::reset ( X *  p = 0 )

inline

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

template<class X>

static void ACE_Intrusive_Auto_Ptr< X >::unspecified_bool ( ACE_Intrusive_Auto_Ptr< X > ***  )

inlinestaticprotected

Used to define a proper boolean conversion for "if (sp) ...".
