-/**
- * A {@link FileTreeIterator} used in tests which allows to specify explicitly
- * what will be returned by {@link #getEntryLastModified()}. This allows to
- * write tests where certain files have to have the same modification time.
- * <p>
- * This iterator is configured by a list of strictly increasing long values
- * t(0), t(1), ..., t(n). For each file with a modification between t(x) and
- * t(x+1) [ t(x) <= time < t(x+1) ] this iterator will report t(x). For
- * files with a modification time smaller t(0) a modification time of 0 is
- * returned. For files with a modification time greater or equal t(n) t(n) will
- * be returned.
- * <p>
- * This class was written especially to test racy-git problems
