CHeapPtrBase Class

Visual Studio 2012

This class forms the basis for several smart heap pointer classes.

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

template < 
class T, 
class Allocator= CCRTAllocator  
> class CHeapPtrBase

Parameters

T: The object type to be stored on the heap.
Allocator: The memory allocation class to use. By default CRT routines are used to allocate and free memory.

Members

Public Constructors

Name	Description
CHeapPtrBase::~CHeapPtrBase	The destructor.

Public Methods

Name	Description
CHeapPtrBase::AllocateBytes	Call this method to allocate memory.
CHeapPtrBase::Attach	Call this method to take ownership of an existing pointer.
CHeapPtrBase::Detach	Call this method to release ownership of a pointer.
CHeapPtrBase::Free	Call this method to delete an object pointed to by a CHeapPtrBase.
CHeapPtrBase::ReallocateBytes	Call this method to reallocate memory.

Public Operators

Name	Description
CHeapPtrBase::operator T*	The cast operator.
CHeapPtrBase::operator &	The & operator.
CHeapPtrBase::operator ->	The pointer-to-member operator.

Public Data Members

Name	Description
CHeapPtrBase::m_pData	The pointer data member variable.

Remarks

This class forms the basis for several smart heap pointer classes. The derived classes, for example, CHeapPtr and CComHeapPtr, add their own constructors and operators. See these classes for implementation examples.
