Serialization is used for object persitence. using this you
can store your object current state in disk. The same state
you can get after restarting your application.

A serializable class usually has a Serialize member
function, and it usually uses the DECLARE_SERIAL and
IMPLEMENT_SERIAL macros, as described under class CObject.

The overloaded extraction (>>) and insertion (<<) operators
are convenient archive programming interfaces that support
both primitive types and CObject-derived classes.

Answer / rck

serialization means writing data to the file and reading
data from the file.
This is supported by CArchive class and the function is
serialize()

serialize function is like
if(ar.IsStoring())
{
//code for storing data
}
else(ar.IsLoading())
{
//Code for loading data
}

Answer / ctharam

Serialization means conversion of Objects from bytes into streaming...and store those data in a External storage like Hard Disk.

Serialize is called by CArchive::ReadObject and CArchive::WriteObject.


Use CArchive::IsLoading or CArchive::IsStoring to determine whether the archive is loading or storing.

IsStoring():-
-------------

// example for CObject::Serialize
void CAge::Serialize( CArchive& ar )
{
CObject::Serialize( ar );
if( ar.IsStoring() )
ar << m_years;
else
ar >> m_years;
}


IsLoading() :-
---------------

int i;
extern CArchive ar;
if( ar.IsLoading() )
ar >> i;
else
ar << i;

Serialization is a process used to read and write object
from and to secondary storage device respectively.Base
class is CArchive class of MFC. it is used basically in
doc-view architecture programming.DECLARE_SERIAL and
IMPLEMENT_SERIAL macro is used in header and .cpp file
respectively, which has to be serialize.

Answer / abhijit

Adding to the above mentioned points i would like to add
the following:

Serialize() function has to be overridden to take advantage
of serialisation support

DECLARE_SERIAL macro provides prototypes for serialisation
functions
