Return Value
A CArchive reference that enables multiple insertion operators on a single line.
Remarks
The last two versions above are specifically for storing 64-bit integers.
If you used the IMPLEMENT_SERIAL macro in your class implementation, then the insertion operator overloaded for CObject calls the protected WriteObject. This function, in turn, calls the Serialize function of the class.
The CStringT insertion operator (<<) supports diagnostic dumping and storing to an archive.
Example
This example demonstrates the use of the CArchive insertion operator << with the int and long types.
long l = 5;
int i = 10;
if(ar.IsStoring())
ar << l << i;
This example 2 demonstrates the use of the CArchive insertion operator << with the CStringT type.
CString s("abc");
ar << s; // Prints the value (abc)
