values
public static MaybeBoolean[] 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 (MaybeBoolean c : MaybeBoolean.values())
System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in
the order they are declared
valueOf
public static MaybeBoolean 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 MaybeBoolean valueOf(boolean b)
booleanValue
public static java.lang.Boolean booleanValue(MaybeBoolean b)

public static MaybeBoolean consensus(boolean a,
boolean b)
