Detailed Description

template<class T>
class OFauto_ptr< T >

a simple class which makes sure a pointer is deleted once it goes out of scope.

This class does NOT do reference counting! This is a reimplementation of std::auto_ptr.

Constructor & Destructor Documentation

template<class T>

OFauto_ptr< T >::OFauto_ptr ( T *  p = NULL )

inlineexplicit

constructs a OFauto_ptr from the given pointer.

You must not call delete on a pointer that is managed by OFauto_ptr!

Parameters

p	the pointer

template<class T>

OFauto_ptr< T >::OFauto_ptr ( OFauto_ptr< T > &  other )

inline

constructs a OFauto_ptr from another OFauto_ptr.

The other OFauto_ptr will be invalidated. This means he will point to NULL from now on!

Parameters

other

the OFauto_ptr to get the pointer from.

template<class T>

OFauto_ptr< T >::OFauto_ptr ( OFauto_ptr_ref< T >  other )

inline

constructs a OFauto_ptr from an OFauto_ptr_ref.

Parameters

other

the OFauto_ptr_ref to get the pointer from.

template<class T>

OFauto_ptr< T >::~OFauto_ptr ( )

inline

destructor.

Destroys the pointer that is managed by this instance, if there is any.

Member Function Documentation

template<class T>

T* OFauto_ptr< T >::get ( ) const

inline

get the pointer that is managed by this class

Returns

the pointer

Referenced by dcmtk::log4cplus::spi::FactoryRegistry< T >::put().

template<class T>

OFauto_ptr< T >::operator OFauto_ptr_ref< T > ( )

inline

this is used automatically by the compiler, don't call directly

Returns

an OFauto_ptr_ref that stores this object's pointer

References OFauto_ptr< T >::release().

template<class T>

T& OFauto_ptr< T >::operator* ( ) const

inline

dereference the pointer that is managed by this class

Returns

the reference

template<class T>

T* OFauto_ptr< T >::operator-> ( ) const

inline

get the pointer that is managed by this class

Returns

the pointer

template<class T>

OFauto_ptr& OFauto_ptr< T >::operator= ( OFauto_ptr< T > &  other )

inline

assigns the other pointer to this OFauto_ptr

Parameters

other

other OFauto_ptr which will be invalidated

Returns

reference to this object

template<class T>

OFauto_ptr& OFauto_ptr< T >::operator= ( OFauto_ptr_ref< T >  other )

inline

assigns the other pointer to this OFauto_ptr

Parameters

other

other OFauto_ptr_ref

Returns

reference to this object

template<class T>

T* OFauto_ptr< T >::release ( )

inline

release the pointer that is managed by this class.

You are now responsible for destroying that pointer yourself!

Returns

the pointer

Referenced by OFauto_ptr< T >::operator OFauto_ptr_ref< T >(), and OFauto_ptr< DecoderStrategy >::operator=().

template<class T>

void OFauto_ptr< T >::reset ( T *  p = NULL )

inline

assign another pointer to this OFauto_ptr, possibly deleting our current pointer

Parameters

p	the new pointer
