    - #### REQUIRES

          public static final ModuleElement.DirectiveKind REQUIRES

      A "requires (static|transitive)* module-name" directive.

    - #### EXPORTS

          public static final ModuleElement.DirectiveKind EXPORTS

      An "exports package-name [to module-name-list]" directive.

    - #### OPENS

          public static final ModuleElement.DirectiveKind OPENS

      An "opens package-name [to module-name-list]" directive.

    - #### USES

          public static final ModuleElement.DirectiveKind USES

      A "uses service-name" directive.

      A "provides service-name with implementation-name" directive.

  - ### Method Detail

    - #### values

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

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

    - #### valueOf

          public static ModuleElement.DirectiveKind 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
