Class DefaultNoteMerger

java.lang.Object

org.eclipse.jgit.notes.DefaultNoteMerger

All Implemented Interfaces:

NoteMerger

public class DefaultNoteMerger
extends Object
implements NoteMerger

Default implementation of the NoteMerger.

If ours and theirs are both non-null, which means they are either both edits or both adds, then this merger will simply join the content of ours and theirs (in that order) and return that as the merge result.

If one or ours/theirs is non-null and the other one is null then the non-null value is returned as the merge result. This means that an edit/delete conflict is resolved by keeping the edit version.

If both ours and theirs are null then the result of the merge is also null.
