[Jython-users] How to set up a trace function ...

[Nicola de C. <nde...@rs...>]

Hi all,

I am trying to access the functionality offered by this simple jython 
command

 >> sys.settrace(MyTraceBackFunction())

from a java program that runs a Jython interpreter .
I tried the following :

PySystemState s = Py.getSystemState();
s.settrace(new MyTraceBackFunction());


Where  MyTraceBackFunction is defined as follow:

  public class MyTraceBackFunction extends PyObject {

        public PyObject __call__(PyFrame frame, PyString name, PyObject 
arg) {
          // do something here.
          return this;
        }
  }


However it doesn't work ...
I couldn't find any example about it .. could you point me to the rigth 
direction ?

Thanks in advance

Nicola
