Class 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.

      • merge

        public Note merge​(Note base,

                          Note theirs,
                          ObjectReader reader,
                          ObjectInserter inserter)
                   throws IOException
        Merges the conflicting note changes.

        base, ours and their are all notes on the same object.

        Specified by:
        merge in interface NoteMerger
        Parameters:
        base - version of the Note
        ours - version of the Note
        theirs - version of the Note
        reader - the object reader that must be used to read Git objects
        inserter - the object inserter that must be used to insert Git objects
        Returns:
        the merge result
        Throws:
        NotesMergeConflictException - in case there was a merge conflict which this note merger couldn't resolve
        IOException - in case the reader or the inserter would throw an java.io.IOException the implementor will most likely want to propagate it as it can't do much to recover from it
