public interface TwoWayKey2StringMapper extends Key2StringMapper
Extends Key2StringMapper and allows a bidirectional transformation between keys and Strings. Note that the object instance created by getKeyMapping(String) is guaranteed to be equal to the original object used to generate the String, but not necessarily the same object reference.

The following condition should be satisfied by implementations of this interface: assert key.equals(mapper.getKeyMapping(mapper.getStringMapping(key)));
