public class AsArrayTypeDeserializer
extends TypeDeserializerBase

Type deserializer used with JsonTypeInfo.As.WRAPPER_ARRAY inclusion mechanism. Simple since JSON structure used is always the same, regardless of structure used for actual value: wrapping is done using a 2-element JSON Array where type id is the first element, and actual object data as second element.

Constructor Detail

AsArrayTypeDeserializer

public AsArrayTypeDeserializer(JavaType bt,
                               TypeIdResolver idRes,
                               BeanProperty property)
Method Detail

getTypeInclusion

public JsonTypeInfo.As getTypeInclusion()
Description copied from class: TypeDeserializer
Accessor for type information inclusion method that deserializer uses; indicates how type information is (expected to be) embedded in JSON input.

Specified by:
getTypeInclusion in class TypeDeserializerBase

deserializeTypedFromArray

public Object deserializeTypedFromArray(JsonParser jp,
                                        DeserializationContext ctxt)
                                 throws IOException,
                                        JsonProcessingException
Method called when actual object is serialized as JSON Array.

Specified by:
deserializeTypedFromArray in class TypeDeserializer
Throws:
IOException
JsonProcessingException

deserializeTypedFromObject

public Object deserializeTypedFromObject(JsonParser jp,
                                         DeserializationContext ctxt)
                                  throws IOException,
                                         JsonProcessingException
Method called when actual object is serialized as JSON Object

Specified by:
deserializeTypedFromObject in class TypeDeserializer
Throws:
IOException
JsonProcessingException

deserializeTypedFromScalar

public Object deserializeTypedFromScalar(JsonParser jp,
                                         DeserializationContext ctxt)
                                  throws IOException,
                                         JsonProcessingException
Description copied from class: TypeDeserializer
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. Method needs to figure out intended polymorphic type, locate JsonDeserializer to use, and call it with JSON data to deserializer (which does not contain type information).

Specified by:
deserializeTypedFromScalar in class TypeDeserializer
Throws:
IOException
JsonProcessingException

deserializeTypedFromAny

public Object deserializeTypedFromAny(JsonParser jp,
                                      DeserializationContext ctxt)
                               throws IOException,
                                      JsonProcessingException
Description copied from class: TypeDeserializer
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). Should only be called if JSON serialization is polymorphic (not Java type); for example when using JSON node representation, or "untyped" Java object (which may be Map, Collection, wrapper/primitive etc).

Specified by:
deserializeTypedFromAny in class TypeDeserializer
Throws:
IOException
JsonProcessingException

_locateTypeId

protected final String _locateTypeId(JsonParser jp,
                                     DeserializationContext ctxt)
                              throws IOException,
                                     JsonProcessingException
Throws:
IOException
JsonProcessingException
