      • close

        void close()
    throws Exception
        Deprecated.
        Tear-down method for the user code. It is called after the last call to the main working methods. For functions that are part of an iteration, this method will be invoked after each iteration superstep.

        This method can be used for clean up work.

        Throws:
        Exception - The function may throw exceptions which cause the streaming program to fail and go into recovery.
