com.hp.util.codec.EnumCodec<E>

Type Parameters:

E - enumeration class

public class EnumCodec<E extends Enum<E>>
extends Object

This class provides the ability to encode and decode enumeration constants to a short string form. It uses a StringSetCodec behind the scenes to do the mapping, but provides methods in terms of the enumeration constants.
