All Implemented Interfaces:

public enum Ternary
extends Enum<Ternary>

The Ternary enumeration implements three-valued logic (also known as tri-state or trits). Specifically, it is used for filtering binary attributes (such as whether a method is static or not) in a way that allows to express that the attribute is present (TRUE), absent (FALSE), or irrelevant for filtering (EITHER).

Returns:

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

valueOf

public static Ternary 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.)
