      • hash

        public int hash​(RawText seq,
                        int lno)
        Description copied from class: SequenceComparator
        Get a hash value for an item in a sequence. If two items are equal according to this comparator's SequenceComparator.equals(Sequence, int, Sequence, int) method, then this hash method must produce the same integer result for both items. It is not required for two items to have different hash values if they are unequal according to the equals() method.
        Specified by:
        hash in class SequenceComparator<RawText>
        seq - the sequence.
        lno - the item to obtain the hash for.
        hash the hash value.
      • reduceCommonStartEnd

        public Edit reduceCommonStartEnd​(RawText a,
                                         RawText b,
                                         Edit e)
        Modify the edit to remove common leading and trailing items. The supplied edit e is reduced in size by moving the beginning A and B points so the edit does not cover any items that are in common between the two sequences. The ending A and B points are also shifted to remove common items from the end of the region.
        reduceCommonStartEnd in class SequenceComparator<RawText>
        a - the first sequence.
        b - the second sequence.
        e - the edit to start with and update.
        e if it was updated in-place, otherwise a new edit containing the reduced region.
      • hashRegion

        protected abstract int hashRegion​(byte[] raw,
                                          int ptr,
                                          int end)
        Compute a hash code for a region.
        raw - the raw file content.
        ptr - first byte of the region to hash.
        end - 1 past the last byte of the region.
        hash code for the region [ptr, end) of raw.
