such as an invertible comparator and a compound comparator.
Classes
BooleanComparator |
A Comparator for Boolean objects that can sort either true or false first. |
ComparableComparator<T extends Comparable<T>> |
Comparator that adapts Comparables to the Comparator interface. |
CompoundComparator<T> |
A comparator that chains a sequence of one or more more Comparators. |
InvertibleComparator<T> |
A decorator for a comparator, with an "ascending" flag denoting
whether comparison results should be treated in forward (standard
ascending) order or flipped for reverse (descending) order. |
NullSafeComparator<T> |
A Comparator that will safely compare nulls to be lower or higher than
