Interface LabeledEnum

All Superinterfaces:: Comparable, Serializable

All Known Implementing Classes:: AbstractGenericLabeledEnum, AbstractLabeledEnum, LetterCodedLabeledEnum, ShortCodedLabeledEnum, StaticLabeledEnum, StringCodedLabeledEnum

public interface LabeledEnum
extends Comparable, Serializable
extends Comparable, Serializable

A interface for objects that represent a labled enumeration. Each such enum instance has the following characteristics:

A type that identifies the enum's class. For example: com.mycompany.util.FileFormat.
A code that uniquely identifies the enum within the context of its type. For example: "CSV". Different classes of codes are possible (Character, Integer, String).
A descriptive label. For example: "the CSV File Format".
