jmri.jmrit.automat
Class JythonAutomaton

java.lang.Object
  jmri.jmrit.automat.AbstractAutomaton
      jmri.jmrit.automat.JythonAutomaton

All Implemented Interfaces:

Runnable

public class JythonAutomaton
extends AbstractAutomaton

This sample Automaton invokes a Jython interpreter to handle a script.

Access is via Java reflection so that both users and developers can work without the jython.jar file in the classpath. To make it easier to read the code, the "non-reflection" statements are in the comments
