java.lang.Objectorg.codehaus.jackson.map.TypeDeserializer
public abstract class TypeDeserializer
Interface for deserializing type information from JSON content, to type-safely deserialize data into correct polymorphic instance (when type inclusion has been enabled for type handled).
Separate deserialization methods are needed because serialized
form for inclusion mechanism JsonTypeInfo.As#PROPERTY
is slighty different if value is not expressed as JSON Object:
and as such both type deserializer and serializer need to
JSON Object form (array, object or other (== scalar)) being
used.

abstract Object |
deserializeTypedFromAny(JsonParser jp,
DeserializationContext ctxt)
Method called to let this type deserializer handle deserialization of "typed" object, when value itself may have been serialized using any kind of JSON value (Array, Object, scalar). |
abstract Object |
deserializeTypedFromArray(JsonParser jp,
DeserializationContext ctxt)
Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Array (regardless of Java type). |
abstract Object |
deserializeTypedFromObject(JsonParser jp,
DeserializationContext ctxt)
Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Object (regardless of Java type). |
abstract Object |
deserializeTypedFromScalar(JsonParser jp,
DeserializationContext ctxt)
Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as a scalar JSON value (something other than Array or Object), regardless of Java type. |
abstract String |
getPropertyName()
Name of property that contains type information, if property-based inclusion is used. |
abstract TypeIdResolver |
getTypeIdResolver()
Accessor for object that handles conversions between types and matching type ids. |
abstract JsonTypeInfo.As |
getTypeInclusion()
Accessor for type information inclusion method that deserializer uses; indicates how type information is (expected to be) embedded in JSON input. |
