Class KeplerConfigurationApplication

java.lang.Object

ptolemy.actor.gui.ConfigurationApplication

org.kepler.KeplerConfigurationApplication

All Implemented Interfaces:

ExecutionListener

public class KeplerConfigurationApplication
extends ConfigurationApplication

This class is the startup class for all non-gui applications of kepler. It handles the command line interface and executes the proper base class in ptolemy. This application supports executing kepler when the -nogui AND -cache command line flags are set. See org.kepler.Kepler.parseArgsAndRun() to see how this application is launched. The reason this application needs to exist is so Kepler can startup a headless runtime with the configuration system in place. Without the configuration, the cache cannot be started. This is working around a limitation in Ptolemy where the GUI generally needs to be instantiated in order to get an instance of Configuration. This class could possibly go away after the new configuration system comes on line if we can pull the configuration options needed for the cache. You can execute this class with the following command: ./kepler.sh -runwf -nogui -cache workflow.xml To generate the kepler.sh script, run 'ant startup-script' from the build-area.
