Class RowLink2

  • All Implemented Interfaces:
    java.lang.Comparable<RowLink>
    public class RowLink2
extends RowLink
    RowLink subclass which specifically contains two items (a pair).

    As well as standard RowLink functionality, this object can also contain a 'score', which is an uninterpreted number. Typically this is used to record how good the match represented by a link is. This value is not taken account of in either compareTo, equals or hashCode methods.
