## Enum Normalizer.Form

- java.lang.Object
- - java.lang.Enum<Normalizer.Form>
  - - java.text.Normalizer.Form

- All Implemented Interfaces:
    Serializable, Comparable<Normalizer.Form>
  Enclosing class:
    Normalizer

      public static enum Normalizer.Form
      extends Enum<Normalizer.Form>

  This enum provides constants of the four Unicode normalization forms that are described in Unicode Standard Annex #15 — Unicode Normalization Forms and two methods to access them.
  Since:
    1.6

    - #### NFD

          public static final Normalizer.Form NFD

      Canonical decomposition.

    - #### NFC

          public static final Normalizer.Form NFC

      Canonical decomposition, followed by canonical composition.

    - #### NFKD

          public static final Normalizer.Form NFKD

      Compatibility decomposition.

    - #### NFKC

          public static final Normalizer.Form NFKC

      Compatibility decomposition, followed by canonical composition.

  - ### Method Detail

    - #### values

          public static Normalizer.Form[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (Normalizer.Form c : Normalizer.Form.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static Normalizer.Form valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null
