A CArchive reference that enables multiple extraction operators on a single line.

The last two versions above are specifically for loading 64-bit integers.

If you used the IMPLEMENT_SERIAL macro in your class implementation, then the extraction operators overloaded for CObject call the protected ReadObject function (with a nonzero run-time class pointer). This function, in turn, calls the Serialize function of the class.

The CStringT extraction operator (>>) supports loading from an archive.

Example

This example demonstrates the use of the CArchive extraction operator >> with the int type.

long l;
int i;
if(ar.IsLoading())
   ar >> l >> i;

Example

This example demonstrates the use of the CArchive insertion and extraction operators << and >> with the CStringT type.

CString s;
if (ar.IsLoading())
   ar >> s;
