Enum Constant Detail

TRUE

public static final TruthValueTracingUtil.TruthValue TRUE

True.

FALSE

public static final TruthValueTracingUtil.TruthValue FALSE

False.

Method Detail

values

public static TruthValueTracingUtil.TruthValue[] 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 (TruthValueTracingUtil.TruthValue c : TruthValueTracingUtil.TruthValue.values())
    System.out.println(c);

Returns:

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

valueOf

public static TruthValueTracingUtil.TruthValue 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

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<TruthValueTracingUtil.TruthValue>

Returns:

and

public static TruthValueTracingUtil.TruthValue and(TruthValueTracingUtil.TruthValue left,
                                                   TruthValueTracingUtil.TruthValue right)

Computes the and value.

Parameters:

left - The left TruthValueTracingUtil.TruthValue.

right - The right TruthValueTracingUtil.TruthValue.

Returns:

The computed and value.

imp

public static TruthValueTracingUtil.TruthValue imp(TruthValueTracingUtil.TruthValue left,
                                                   TruthValueTracingUtil.TruthValue right)

Computes the imp value.

Parameters:

left - The left TruthValueTracingUtil.TruthValue.

right - The right TruthValueTracingUtil.TruthValue.

Returns:

The computed imp value.

or

public static TruthValueTracingUtil.TruthValue or(TruthValueTracingUtil.TruthValue left,
                                                  TruthValueTracingUtil.TruthValue right)

Computes the or value.

Parameters:

left - The left TruthValueTracingUtil.TruthValue.

right - The right TruthValueTracingUtil.TruthValue.

Returns:

The computed or value.

not

public static TruthValueTracingUtil.TruthValue not(TruthValueTracingUtil.TruthValue value)

Computes the not value.

Parameters:

value - The TruthValueTracingUtil.TruthValue.

Returns:

The computed not value.

eqv

public static TruthValueTracingUtil.TruthValue eqv(TruthValueTracingUtil.TruthValue left,
                                                   TruthValueTracingUtil.TruthValue right)

Computes the eqv value.

Parameters:

value - The TruthValueTracingUtil.TruthValue.

Returns:

The computed not value.

ifThenElse

public static TruthValueTracingUtil.TruthValue ifThenElse(TruthValueTracingUtil.TruthValue conditionValue,
                                                          TruthValueTracingUtil.TruthValue thenValue,
                                                          TruthValueTracingUtil.TruthValue elseValue)
