    • Method Detail

      • accept

        void accept(OutputStream stream,
            VaadinSession session)
     throws IOException

        Handles stream (writes data to it) using session as a context.

        Note that the method is not called under the session lock. It means that if implementation requires access to the application/session data then the session has to be locked explicitly.

        Parameters:

        stream - data output stream

        session - vaadin session

        Throws:

        IOException - if an IO error occurred
