    • Method Detail

      • getChecksum

        public abstract long getChecksum()
                                  throws IOException
        Returns the current checksum value
      • seek

        public void seek​(long pos)
                  throws IOException
        Sets current position in this file, where the next read will occur. If this is beyond the end of the file then this will throw EOFException and then the stream is in an undetermined state.

        ChecksumIndexInput can only seek forward and seeks are expensive since they imply to read bytes in-between the current position and the target position in order to update the checksum.
