7  * for deserializer Map keys of various types, from JSON property names.
8  * Access is by a single callback method; instance is to either return
9  * a configured {@link KeyDeserializer} for specified type, or null to indicate that it
10  * does not support handling of the type. In latter case, further calls can be made
11  * for other providers; in former case returned key deserializer is used for handling of
12  * key instances of specified type.
