Imports

java.io.IOException, .Serializable, java.lang.reflect.Constructor, .Method, java.net.MalformedURLException, .URI, .URL, java.util.*, tools.jackson.core.JacksonException, .JsonParser, tools.jackson.core.io.NumberInput, tools.jackson.databind.*, tools.jackson.databind.annotation.JacksonStdImpl, tools.jackson.databind.cfg.EnumFeature, .MapperConfig, tools.jackson.databind.introspect.AnnotatedClass, .AnnotatedMethod, tools.jackson.databind.util.ClassUtil, .EnumResolver, .TokenBuffer

Default KeyDeserializer implementation used for most java.util.Map key 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).

Nested and Inner Type Summary

Modifier and Type	Class and Description
pack-priv static class	JDKKeyDeserializer.DelegatingKD Key deserializer that wraps a "regular" deserializer (but one that must recognize FIELD_NAMEs as text!) to reuse existing handlers as key handlers.
pack-priv static class	JDKKeyDeserializer.EnumKD
pack-priv static class	JDKKeyDeserializer.StringCtorKeyDeserializer Key deserializer that calls a single-string-arg constructor to instantiate desired key type.
pack-priv static class	JDKKeyDeserializer.StringFactoryKeyDeserializer Key deserializer that calls a static no-args factory method to instantiate desired key type.
