Detailed Description

template<typename T>
class auto_array< T >

Limited version of std::auto_ptr for dynamic arrays.

As you know, one cannot use std::auto_ptr for storing dynamic arrays because std::auto_ptr calls delete instead of delete[] in its destructor. This version provides the same functinality for dynamic arrays.

Todo:

Only a limited support is currently available, so add the rest of the functionality that is provided by the std::auto_ptr template class.

Constructor & Destructor Documentation

template<typename T>

auto_array< T >::auto_array ( T *  p = 0 ) throw ( )

inlineexplicit

Constructs an auto_array object from an array pointer.

Parameters

p	Pointer to a dynamically allocated array. If this parameter is 0 the auto_array is a null pointer (points to nowhere).

template<typename T>

auto_array< T >::~auto_array ( ) throw ( )

inline

Deallocates the block of memory the object "points to" using delete[] and destructs the object.

Member Function Documentation

template<typename T>

T* auto_array< T >::get ( ) const throw ( )

inline

Returns the stored pointer.

Returns

Pointer to the array pointed by the auto_array object, if any, or zero if it does not point to any array.

template<class Y >

private

template<typename T>

T* auto_array< T >::release ( ) throw ( )

inline

Returns the stored pointer and sets the internal pointer to 0.

Returns

Pointer to the array pointed by the auto_array object, if any, or zero if it does not point to any array.

Sets the auto_array internal pointer to null pointer (which indicates it points to no array) without destructing the array currently pointed by the auto_array.

References auto_array< T >::_p.

template<typename T>

void auto_array< T >::reset ( T *  p = 0 ) throw ( )

inline

Deallocates the array that the auto_array points to and sets a new value.

Destructs the array pointed by the auto_array object, if any, and deallocates its memory (by calling operator delete[]). If a value for p is specified, the internal pointer is initialized to that value (otherwise it is set to the null pointer).

References auto_array< T >::_p.
