jmri.jmrit.automat
Class JythonSiglet

java.lang.Object
  jmri.jmrit.automat.AbstractAutomaton
      jmri.jmrit.automat.Siglet
          jmri.jmrit.automat.JythonSiglet

All Implemented Interfaces:

Runnable

public class JythonSiglet
extends Siglet

This sample Automaton invokes a Jython interpreter to handle a script that defines a Siglet implementation.

The python file should define two functions:

• defineIO()
• setOutput()

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.

Constructor Detail

JythonSiglet

public JythonSiglet(String file)

Method Detail

defineIO

public void defineIO()

Initialize this object.

• Create the Python interpreter.
• Load the generally-available objects
• Read the file
• Run the python defineIO routine

Initialization of the Python in the actual script file is deferred until the Siglet.handle() method.

Overrides:

defineIO in class Siglet

setOutput

public void setOutput()

Invoke the Jython setOutput function

Overrides:

setOutput in class Siglet
