All Implemented Interfaces:

Iterable<HGHandle>, HGLink

public class HGBergeLink
extends HGPlainLink

A HGBergeLink represent a hyperarc or hyperedge in the mathematical theory of hypergraphs. A hyperarc has a target set that is partitioned into a head and a tail. The name comes from the presumed inventor of this type of arc, Claude Berge. If it turns out the latter did not actually come up with the definition, too bad for the naming choice :)
