Enum Bool

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<Bool>
    public enum Bool
extends java.lang.Enum<Bool>
    Three-valued (true, false, unknown) boolean type. The standard boolean operators are supported. The following truth table gives the results the unary negation operator: 
        not
 T   F
 F   T
 U   U
    The truth table for boolean operators is as follows: 
           and or
 T  T   T   T
 T  F   F   T
 T  U   U   T
 F  F   F   F
 F  U   U   U
 U  U   U   U

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

      • valueOf

        public static Bool 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

      • valueOf

        public static Bool valueOf​(boolean value)
        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:
        value - 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
