public class StdKeyDeserializer extends KeyDeserializer implements Serializable
KeyDeserializer
implementation used for most Map
types Jackson supports.
Implemented as "chameleon" (or swiss pocket knife) class; not particularly elegant,
but helps reduce number of classes and jar size (class metadata adds significant
per-class overhead; much more than bytecode).KeyDeserializer.None
