Method Detail

init

public void init(DBManLocalI _dbm,
                 netrexx.lang.Rexx _section)

processConfChangeEvent

public void processConfChangeEvent(ConfChangeEvent e)

Description copied from interface: ConfChangeEventListenerI

Processes a configuration change event.

Specified by:

processConfChangeEvent in interface ConfChangeEventListenerI

Parameters:

e - The ConfChangeEvent object containing details of the configuration change.

getPersistenceHandler

public abstract PersistenceHandlerI getPersistenceHandler(AbstractKeyGenerator keygen)

Creates and returns a new PersistenceHandlerI configured strictly for read-only operations.

This handler is only for loading/retrieving objects from the database. It does not support transaction commits; any modifications made to objects loaded via this handler cannot be saved back to the database through this instance.

Parameters:

keygen - The AbstractKeyGenerator to use.

Returns:

A new read-only handler instance.

getPersistenceHandlerForSaving

public abstract PersistenceHandlerI getPersistenceHandlerForSaving(AbstractKeyGenerator keygen)

Creates and returns a new PersistenceHandlerI configured for transactional read-write operations.

This handler supports both loading objects and persisting changes (saving) back to the database. Use this method when the intended logic involves modifying data within a specific transaction context.

Parameters:

keygen - The AbstractKeyGenerator to use.

Returns:

A new read-write handler instance capable of committing transactions.
