      • values

        public static Boolean3[] 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 (Boolean3 c : Boolean3.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static Boolean3 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

      • toBoolean

        public java.lang.Boolean toBoolean()
        Convert the three valued boolean to a two valued boolean object.

      • isTrue

        public boolean isTrue()
        Check if explicitly set to true, i.e. neither FALSE nor NULL.
