IMPLEMENT_SERIAL
Generates the C++ code necessary for a dynamic CObject-derived class with run-time access to the class name and position within the hierarchy.
IMPLEMENT_SERIAL(class_name, base_class_name, wSchema )
Параметры
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.
Заметки
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.
