All Implemented Interfaces:

ActionListener, Serializable, Cloneable, EventListener, Action

public class StoreAndCompare
extends AbstractAction

Determine if there have been changes made to the PanelPro data. If so, then a prompt will be displayed to store the data before the JMRI shutdown process proceeds.

If the JMRI application is DecoderPro, the checking does not occur. If the PanelPro tables contain only 3 time related beans and no panels, the checking does not occur.

The main check process uses the checkFile process which is used by the load and store tests. The current configuration is stored to a temporary file. This temp file is compared to the file that was loaded manually or via a start up action. If there are differences and the shutdown store check preference is enabled, a store request prompt is displayed. The prompt does not occur when running in headless mode.
