Package com.fasterxml.jackson.databind.deser.std

Class StdKeyDeserializer

java.lang.Object

com.fasterxml.jackson.databind.KeyDeserializer

com.fasterxml.jackson.databind.deser.std.StdKeyDeserializer

All Implemented Interfaces:

Serializable

public class StdKeyDeserializer
extends KeyDeserializer
implements Serializable

Default 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).
