CAutoPtrElementTraits Class

Article
08/03/2021

This class provides methods, static functions, and typedefs useful when creating collections of smart pointers.

Important

This class and its members cannot be used in applications that execute in the Windows Runtime.

Syntax

template<typename T>
class CAutoPtrElementTraits
    : public CDefaultElementTraits<ATL::CAutoPtr<T>>

Parameters

T
The pointer type.

Members

Public Typedefs

Name	Description
CAutoPtrElementTraits::INARGTYPE	The data type to use for adding elements to the collection class object.
CAutoPtrElementTraits::OUTARGTYPE	The data type to use for retrieving elements from the collection class object.

Remarks

This class provides methods, static functions, and typedefs for aiding the creation of collection class objects containing smart pointers. The classes CAutoPtrArray and CAutoPtrList derive from CAutoPtrElementTraits. If building a collection of smart pointers that requires vector new and delete operators, use CAutoVectorPtrElementTraits instead.
