java.lang.Object
org.forgerock.json.resource.SortKeyComparator
All Implemented Interfaces:
Comparator<JsonValue>
public class SortKeyComparator extends Object implements Comparator<JsonValue>
This comparator iterates through the provided sortKeys and finds the first comparative difference between the left and right side JsonValues. To ensure consistency with sort order, at least one sortKey should be provided that will guarantee uniqueness between two JsonValues. A JsonValue that wraps a null object could be considered either as the lowest possible value (SortKeyComparator.NullPosition.NULL_FIRST, default) or the highest possible value (SortKeyComparator.NullPosition.NULL_LAST).
