      • 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​(java.lang.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,
                            java.lang.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
