NetCOBOL for SPARC Architecture SAF Subroutines User's Guide

68 Chapter 3. How to Use SAF Subroutines
Object method:
• SWEEP-SESSION
This method is called when a session is timed out. It is used to perform
processing such as file closing and database (DB) commitment/rollback.
Method argument:
None
Method return information:
None
Note:
• If a session is timed out, the SAF subroutine calls the SWEEP-SESSION method
and assigns a NULL object to the object reference item which has been
registered in the session data.
• If the default SWEEP-SESSION method is not replaced by a user-written method,
nothing is executed by the SWEEP-SESSION method.
• The COBW3-SESSION-ADAPTER class inherits the FJBASE class.
Example:

METHOD-ID. SWEEP-SESSION OVERRIDE.
DATA DIVISION.
:
PROCEDURE DIVISION.
:
* Write down timeout processing if necessary.
