Package org.eclipse.jgit.diff
Class Subsequence<S extends Sequence>
java.lang.Object
org.eclipse.jgit.diff.Sequence
org.eclipse.jgit.diff.Subsequence<S>
- Type Parameters:
S- the base sequence type.
Wraps a
Sequence to have a narrower range of
elements.
This sequence acts as a proxy for the real sequence, translating element
indexes on the fly by adding begin to them. Sequences of this type
must be used with a SubsequenceComparator.

Subsequence
Construct a subset of another sequence. The size of the subsequence will beend - begin.- Parameters:
base- the real sequence.begin- First element index ofbasethat will be part of this new subsequence. The element atbeginwill be this sequence's element 0.end- One past the last element index ofbasethat will be part of this new subsequence.

Method Details
-
a
Construct a subsequence around the A region/base sequence.- Parameters:
a- the A sequence.region- the region ofato create a subsequence around.- Returns:
- subsequence of
baseas described by A inregion.
-
b
Construct a subsequence around the B region/base sequence.- Parameters:
b- the B sequence.region- the region ofbto create a subsequence around.- Returns:
- subsequence of
baseas described by B inregion.
-
toBase
Adjust the Edit to reflect positions in the base sequence.- Parameters:
e- edit to adjust in-place. Prior to invocation the indexes are in terms of the two subsequences; after invocation the indexes are in terms of the base sequences.a- the A sequence.b- the B sequence.
-
toBase
public static <S extends Sequence> EditList toBase(EditList edits, Subsequence<S> a, Subsequence<S> b) Adjust the Edits to reflect positions in the base sequence.- Parameters:
edits- edits to adjust in-place. Prior to invocation the indexes are in terms of the two subsequences; after invocation the indexes are in terms of the base sequences.a- the A sequence.b- the B sequence.- Returns:
- always
edits(as the list was updated in-place).
