public final Class Subsequence<S extends Sequence>

extends Sequence
Class Inheritance
Type Parameters
<S>
the base sequence type.
Wraps a org.eclipse.jgit.diff.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 org.eclipse.jgit.diff.SubsequenceComparator.

Constructor Detail

Subsequenceback to summary
public Subsequence(S base, int begin, int end)

Construct a subset of another sequence. The size of the subsequence will be end - begin.

Parameters
base:S

the real sequence.

begin:int

First element index of base that will be part of this new subsequence. The element at begin will be this sequence's element 0.

end:int

One past the last element index of base that will be part of this new subsequence.
