hashback to summary
public int hash(RawText seq, int lno)

Implements abstract org.eclipse.jgit.diff.SequenceComparator.hash.

Doc from org.eclipse.jgit.diff.SequenceComparator.hash.

Get a hash value for an item in a sequence. If two items are equal according to this comparator's 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.

Parameters
seq:RawText

the sequence.

lno:int

the item to obtain the hash for.

Returns:int

hash the hash value.

hashRegionback to summary
protected abstract int hashRegion(byte[] raw, int ptr, int end)

Compute a hash code for a region.

Parameters
raw:byte[]

the raw file content.

ptr:int

first byte of the region to hash.

end:int

1 past the last byte of the region.

Returns:int

hash code for the region [ptr, end) of raw.

reduceCommonStartEndback to summary
public Edit reduceCommonStartEnd(RawText a, RawText b, Edit e)

Overrides org.eclipse.jgit.diff.SequenceComparator.reduceCommonStartEnd.

Doc from org.eclipse.jgit.diff.SequenceComparator.reduceCommonStartEnd.

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.

Parameters
a:RawText

the first sequence.

b:RawText

the second sequence.

e:Edit

the edit to start with and update.

Returns:Edit

e if it was updated in-place, otherwise a new edit containing the reduced region.
