Enum Constant Detail

TRUE

public static final Truthiness TRUE

Definitely true

PROBABLY

public static final Truthiness PROBABLY

We are not sure, but we guess it's true

UNKNOWN

public static final Truthiness UNKNOWN

We really don't know

MAYBE_NOT

public static final Truthiness MAYBE_NOT

It might be true, but provisionally we think it's not. E.g. the condition may become true for some later reason.

FALSE

public static final Truthiness FALSE

Method Detail

values

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

Returns:

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

valueOf

public static Truthiness valueOf(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:

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

NullPointerException - if the argument is null

of

public static Truthiness of(boolean boolValue)

maybe

public static Truthiness maybe(boolean boolValue)

getAsBoolean

public boolean getAsBoolean()

Specified by:

getAsBoolean in interface BooleanSupplier
