## org.springframework.core.enums
Interface LabeledEnum

All Superinterfaces:
  Comparable, Serializable

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

    public interface LabeledEnum

extends Comparable, Serializable

An interface for objects that represent a labeled 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 (e.g., Character, Integer, String).
- A descriptive label. For example: "the CSV File Format".

Field Detail

### CODE_ORDER

    static final Comparator CODE_ORDER

  Shared Comparator instance that sorts enumerations by `CODE_ORDER`.

### LABEL_ORDER

    static final Comparator LABEL_ORDER

  Shared Comparator instance that sorts enumerations by `LABEL_ORDER`.

### DEFAULT_ORDER

    static final Comparator DEFAULT_ORDER

  Shared Comparator instance that sorts enumerations by `LABEL_ORDER`, then `CODE_ORDER`.

Method Detail

### getType

    Class getType()

  Return this enumeration's type.

### getCode

    Comparable getCode()

  Return this enumeration's code.

  Each code should be unique within enumerations of the same type.

### getLabel

    String getLabel()

  Return a descriptive, optional label.
