All Implemented Interfaces:

Comparator<Entity>

public class FieldComparator
extends Object
implements Comparator<Entity>

Most applications require a kind of natural ordening within the set of objects. The EntityContext may contain a single field or a list of fields that control the fields by which the set of objects should be ordered before rendering. To perform the ordening, an instance of the current FieldComparator class is created to compare two Entities with respect to the values of their order field(s).
