DECLARE_SERIAL

Article
12/01/2015

Generates the C++ header code necessary for a CObject-derived class that can be serialized.

Syntax

DECLARE_SERIAL(
class_name )

Parameters

class_name
The actual name of the class.

Remarks

Serialization is the process of writing or reading the contents of an object to and from a file.

Use the DECLARE_SERIAL macro in an .h module, and then include that module in all .cpp modules that need access to objects of this class.

If DECLARE_SERIAL is included in the class declaration, then IMPLEMENT_SERIAL must be included in the class implementation.

The DECLARE_SERIAL macro includes all the functionality of DECLARE_DYNAMIC and DECLARE_DYNCREATE.

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 on the DECLARE_SERIAL macro, see CObject Class Topics.

Example

class CAge : public CObject
{
public:
    void Serialize(CArchive& ar);
    DECLARE_SERIAL(CAge)

    // remainder of class declaration omitted

Requirements

Header: afx.h
