      • values

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

        public static NullValue valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • getNullValue

        public static NullValue getNullValue​(java.lang.String value)
        Obtain a NullValue for the given name by value
        Parameters:
        value - the name
        Returns:
        the NullValue found or NullValue.NONE if not found. If value is null, returns NullValue.NONE.
