Interface Feature

All Superinterfaces:

java.lang.Comparable, SwingRepresentable

All Known Subinterfaces:

FeatureCollection, FSMFeature

All Known Implementing Classes:

AbstractFeature, AbstractFeatureCollection, AbstractFSMFeature, BooleanFeature, CharacterFeature, DisplayMessageFeature, DoubleFeature, ExceptionFeature, FeatureMap, FiveSeverityFeature, InetAddressFeature, IntegerFeature, LongStringFeature, ObjectFeature, OrderedFeatureMap, PrintQualityFeature, StringFeature, TableFeature, TermVectorFeature, YesNoFeature

public interface Feature
extends java.lang.Comparable, SwingRepresentable

Features are the primary placeholders for information about both problems and solutions. Every Feature instance contains a value, and is governed by exactly one FeatureSpec, linked by FeatureKey.
