Re: [Jython-users] casting a java object created in jython to its true class

[brian z. <bz...@zi...>]

If you have a PyObject and want to get the underlying Java instance, use:

  po.__tojava__(<the Java class you want>)

For instance, say arg is a PyInteger instance, the following would get the
long value:

  long ticks = ((Number) arg.__tojava__(Number.class)).longValue();

Most subclasses (maybe all) of PyObject implement this method and try their
best to give you what you want.  It's amazing thorough for most types.
