IMPLEMENT_SERIAL

  • Article

 

Generates the C++ code necessary for a dynamic CObject-derived class with run-time access to the class name and position within the hierarchy.

Syntax

IMPLEMENT_SERIAL(
class_name
, 
base_class_name
, 
wSchema )

Parameters

  • class_name
    The actual name of the class.

  • base_class_name
    The name of the base class.

  • wSchema
    A UINT "version number" that will be encoded in the archive to enable a deserializing program to identify and handle data created by earlier program versions. The class schema number must not be –1.

Remarks

Use the IMPLEMENT_SERIAL macro in a .cpp module; then link the resulting object code only once.

You can use the AFX_API macro to automatically export the CArchive extraction operator for classes that use the DECLARE_SERIAL and IMPLEMENT_SERIAL macros. Bracket the class declarations (located in the .h file) with the following code:

#undef AFX_API
#define AFX_API AFX_EXT_CLASS

// <your class declarations here>

#undef AFX_API
#define AFX_API

For more information, see the CObject Class Topics.

Example

IMPLEMENT_SERIAL(CAge, CObject, VERSIONABLE_SCHEMA | 2)

Requirements

Header: afx.h
