Class CompositeComparator<T>

java.lang.Object

org.unix4j.util.sort.CompositeComparator<T>

All Implemented Interfaces:

Comparator<T>

public final class CompositeComparator<T>
extends Object
implements Comparator<T>

A comparator based on a list of underlying comparators used in the specified order. If the first underlying comparator returns a value different from 0 indicating non-equality, the value is returned. If all underlying comparators return 0, this composite comparator returns 0.
