                  int len)
           throws java.io.IOException
        Writes array of bytes to the compressed output stream. This method will block until all the bytes are written.
        Overrides:
        write in class java.util.zip.DeflaterOutputStream
        Parameters:
        buf - The data to be written.
        off - The start offset of the data.
        len - The length of the data.
        Throws:
        java.io.IOException - If an I/O error has occurred.

      • finish

        public void finish()
            throws java.io.IOException
        Finishes writing compressed data to the output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream.
        Overrides:
        finish in class java.util.zip.DeflaterOutputStream
        Throws:
        java.io.IOException - if an I/O error has occurred.
