This example shows one way to incorporate a Jython class into a Java
program.
To do this you should follow the following steps:
Note: path names are given for a Unix machine. Make the obvious
translation for Windows.
1. run "jython Graph.py" in this directory
This is just to make sure the Jython code works on your machine
2. run "jythonc --package pygraph Graph.py" in this directory
This should produce the Java class pygraph.Graph. Because this is
only a shallow freeze of the code in Graph.py, you can modify the
actual Python code (and any libraries it depends on) without needed
to perform the freeze process again. You will need to repeat this
freeze process any time you add new methods to the Graph class that
override Java methods in its superclass.
Notice the strange "@sig ..." doc comments on the __init__ and the
setExpression methods. These cause convenient methods to be
created on the Java proxy class.
3. run "javac pygraph/PythonGraph.java"
You must have both the current directory ('.') and the Jython
library directory (<install_dir>\jython.jar) in your CLASSPATH for
this to work.
4. run "java pygraph.PythonGraph"
You need the same classpath as given above
