    • Method Detail

      • incrementByteCount

        void incrementByteCount​(int bytes)
        Add bytes to the total deserialize count. This is called by each BaseType's deserialize method to provide the user with feedback on the number of bytes that have been transferred so far. If some future version of OPeNDAP provides a correct Content-Length, then a sophisticated GUI could use this information to estimate the time remaining to download.
        Parameters:
        bytes - the number of bytes to add.

      • userCancelled

        boolean userCancelled()
        User cancellation status. This returns true when the user has clicked the cancel button of a GUI, or false if the download should proceed. This is called at various cancellation points throughout the deserialize process so that the download can be cancelled in an orderly fashion.
        Returns:
        true if the download should be cancelled.

      • finished

        void finished()
        Download finished notice. This allows the GUI to close itself or print a message to the user that the transfer is finished.
