Method Detail

classDictInit

public static void classDictInit(PyObject dict)

This method is called when the module is loaded, to populate the namespace (dictionary) of the module. The dictionary has been initialised at this point reflectively from the methods of this class and this method nulls those entries that ought not to be exposed.

Parameters:

dict - namespace of the module

UnsupportedOperation

public static PyException UnsupportedOperation(String message)

A function that returns a PyException, which is a Java exception suitable for throwing, and that will be raised as an UnsupportedOperation Python exception.

Parameters:

message - text message parameter to the Python exception

Returns:

nascent UnsupportedOperation Python exception

open

public static PyObject open(PyObject[] args,
            String[] kwds)

Open file and return a stream. Raise IOError upon failure. This is a port to Java of the CPython _io.open (Modules/_io/_iomodule.c) following the same logic, but expressed with the benefits of Java syntax.

Parameters:

args - array of arguments from Python call via Jython framework

kwds - array of keywords from Python call via Jython framework

Returns:

the stream object
