public interface AtomicMatchKey
In general this is used only for equality comparison. Match keys representing atomic values of an ordered type, however, must also implement Comparable, and their compareTo() method must reflect the ordering semantics. In the case of strings this means the keys must reflect the semantics of the relevant collation.
