# ACE_Refcounted_Auto_Ptr< X, ACE_LOCK > Class Template Reference

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...

## 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.

## Constructor & Destructor Documentation

template<class X, class ACE_LOCK>
ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::ACE_Refcounted_Auto_Ptr | ( | X * | p = `0` | ) | `[inline]`

| Constructor that initializes an `ACE_Refcounted_Auto_Ptr` to point to the result immediately.

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 created 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>
ACE_BEGIN_VERSIONED_NAMESPACE_DECL ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::~ACE_Refcounted_Auto_Ptr | ( | void |  | ) | `[virtual]`

| Destructor.

## Member Function Documentation

template<class X, class ACE_LOCK>
int ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::count | ( | void |  | ) | const`[inline]`

| Get the reference count value.

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>
int ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::null | ( | void |  | ) | const`[inline]`

| Allows us to check for NULL on all ACE_Refcounted_Auto_Ptr objects.

X & ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::operator * | ( |  | ) | const`[inline]`

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>
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]`

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

template<class X, class ACE_LOCK>
X * ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::release | ( | void |  | ) | `[inline]`

| Sets the pointer value to 0 and returns its old value.

template<class X, class ACE_LOCK>
void ACE_Refcounted_Auto_Ptr< X, ACE_LOCK >::reset | ( | X * | p = `0` | ) | `[inline]`

| Invokes delete on the previous pointer value and then sets the pointer value to the specified value.
