Hi,
I'm trying to use Jython as a scripting language within an ide. The
ide is for developing simulations with a Java framework, and the
scripting is for scripting simulation behavoir (not ide behavoir).
Ideally, I'd want the user to define a Java class through the ide and
have the behavoir of such a class defined in python. Of course,
there's lots of wrapping etc. going on here, but I'm thinking of
generating bytecode whose source code would look something like
the following:
public class MyAgent {
private PyFunction step;
private int wealth = 0;
public void step() {
step.__call(...);
}
}
where the PyFunction step has the wealth ivar available to it.
The PyFunction would be the result of compiling whatever the user entered
into the ide, for example:
if wealth > 3:
do_something()
else:
do_something_else()
My question then is, is this possible? And if so, how do I create a
PyFunction object and ensure that its namespace / calling frame contains
the appropriate mappings - so that in the above example the PyFunction
has the current value for wealth.
Alternatively, I suppose I could treat the Java class as a
proxy for a PyClass, so that any calls on the Java class are forwarded
to the PyClass so:
public void setWealth(int val) {
target.__setattr__("wealth", new PyInteger(val));
}
Perhaps the PyClass should be a PyInstance here though.
At any rate, the question remains given some jython source code how
can I get a PyFunction, PyClass, or PyInstance from within a
Java application.
thanks very much,
Nick
ps. If this is all woefully wrong-headed, any suggestions would
be appreciated.
