Constructor Detail

ListComparator

public ListComparator()
Creates a ListComparator which compares elements first-to-last. All elements of the list must implement java.lang.Comparable.


ListComparator

public ListComparator(boolean cmpForwards,
                      Comparator elementComparator)
Creates a ListComparator. If cmpForwards is true, compares elements first-to-last, otherwise compares them last-to-first. If elementComparator is null, then all elements of the list must implement java.lang.Comparable and the ListComparator uses their natural ordering. Otherwise, it uses the supplied Comparator to compare elements.
