Enum Class Bool

java.lang.Object

java.lang.Enum<Bool>

com.complexible.common.base.Bool

All Implemented Interfaces:

Serializable, Comparable<Bool>, Constable

public enum Bool
extends 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

Method Details

values

public static Bool[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Bool valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

valueOf

public static Bool valueOf(boolean value)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
