Enum When

  • All Implemented Interfaces:
    Serializable, Comparable<When>

    public enum When
    extends Enum<When>
    Used to describe the relationship between a qualifier T and the set of values S possible on an annotated element. In particular, an issues should be reported if an ALWAYS or MAYBE value is used where a NEVER value is required, or if a NEVER or MAYBE value is used where an ALWAYS value is required.
    • Enum Constant Detail

      • ALWAYS

        public static final When ALWAYS
        S is a subset of T
      • UNKNOWN

        public static final When UNKNOWN
        nothing definitive is known about the relation between S and T
      • MAYBE

        public static final When MAYBE
        S intersection T is non empty and S - T is nonempty
      • NEVER

        public static final When NEVER
        S intersection T is empty
    • Method Detail

      • values

        public static When[] 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 (When c : When.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static When 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
