  • Method Details

    • addComparator

      void addComparator(Traversal.Admin<S,C> traversal, Comparator<C> comparator)
      Add a Traversal-based Comparator to the holder. If no traversal is needed, use IdentityTraversal.
      Parameters:
      traversal - the traversal to pre-process the object by.
      comparator - the comparator to compare the result of the object after traversal processing

    • getComparators

      List<org.javatuples.Pair<Traversal.Admin<S,C>,Comparator<C>>> getComparators()
      Get the comparators associated with this holder. The comparators are ordered according to their oder of operation.
      Returns:
      a list of Traversal/Comparator-pairs
