Method Summary

Modifier and Type	Method	Description
TriBool	conservativeAnd(TriBool triBool)	This method performs a conservative AND of TriBool results It is meant to be used when collapsing the results of testing a single predicate against candidates of a UnionType Therefore, this variation will return UNKNOWN whenever one of the operands is UNKNOWN
boolean	isFalse()
boolean	isTrue()
boolean	isUnknown()
TriBool	logicalAnd(TriBool triBool)	This method performs a logical AND of TriBool results It is meant to be used when performing the logical combination of ANDed predicates against a given type Therefore, this variation behaves like a standard logical "AND" and will return FALSE whenever one of the operands is FALSE
TriBool	or(TriBool triBool)
static TriBool	valueOf(String name)	Returns the enum constant of this class with the specified name.
static TriBool[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Method Details

values

public static TriBool[] 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 TriBool 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

conservativeAnd

public TriBool conservativeAnd(TriBool triBool)

This method performs a conservative AND of TriBool results It is meant to be used when collapsing the results of testing a single predicate against candidates of a UnionType Therefore, this variation will return UNKNOWN whenever one of the operands is UNKNOWN

logicalAnd

public TriBool logicalAnd(TriBool triBool)

This method performs a logical AND of TriBool results It is meant to be used when performing the logical combination of ANDed predicates against a given type Therefore, this variation behaves like a standard logical "AND" and will return FALSE whenever one of the operands is FALSE

or

public TriBool or(TriBool triBool)

isTrue

public boolean isTrue()

isFalse

public boolean isFalse()

isUnknown

public boolean isUnknown()
