  - ### Method Detail

    - #### values

          public static Draft[] 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 (Draft c : Draft.values())
              System.out.println(c);

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

    - #### valueOf

          public static Draft 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

    - #### getIdentifier

          public String getIdentifier()

      Returns:
        the identifier of the draft version.

    - #### from

          public static Draft from​(String string)

      Converts a draft number to a `Draft` enum value.
      Parameters:
        `string` - A draft number, e.g.: `[4|7|8|2019-09|2020-12]`
      Returns:
        a Draft enum value

    - #### fromIdentifier

          public static Draft fromIdentifier​(String string)

      Converts a draft identifier to a `Draft` enum value.
      Parameters:
        `string` - The identifier (in URL format)
      Returns:
        a Draft enum value

    - #### isAfter

          public boolean isAfter​(Draft draft)

      Parameters:
        `draft` - to check against
      Returns:
        true if the draft instance was released after the draft provided.

    - #### isBefore

          public boolean isBefore​(Draft draft)

      Parameters:
        `draft` - to check against
      Returns:
        true if the draft instance was released before the draft provided.
