Enum ConstraintTarget

    • Enum Constant Detail

      • IMPLICIT

        public static final ConstraintTarget IMPLICIT
        Discover the type when no ambiguity is present
        • if neither on a method nor a constructor, it implies the annotated element (type, field etc),
        • if on a method or constructor with no parameter, it implies RETURN_VALUE,
        • if on a method with no return value (void), it implies PARAMETERS.
        Otherwise, IMPLICIT is not accepted and either RETURN_VALUE or PARAMETERS is required. This is the case for constructors with parameters and methods with parameters and return value.

        public static final ConstraintTarget RETURN_VALUE
        Constraint applies to the return value of a method or a constructor.

        public static final ConstraintTarget PARAMETERS
        Constraint applies to the parameters of a method or a constructor
    • Method Detail

      • values

        public static ConstraintTarget[] 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 (ConstraintTarget c : ConstraintTarget.values())
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static ConstraintTarget 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.)
        name - the name of the enum constant to be returned.
        the enum constant with the specified name
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
