- All Implemented Interfaces:
java.io.Serializable
public class AsWrapperTypeDeserializer extends TypeDeserializerBase implements java.io.Serializable
Type deserializer used withJsonTypeInfo.As.WRAPPER_OBJECT
inclusion mechanism. Simple since JSON structure used is always the same, regardless of structure used for actual value: wrapping is done using a single-element JSON Object where type id is the key, and actual object data as the value.- See Also:
- Serialized Form

Method Summary
All Methods Instance Methods Concrete Methods Modifier and Type Method Description java.lang.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).java.lang.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).java.lang.Object
deserializeTypedFromObject(JsonParser jp, DeserializationContext ctxt)
Deserializing type id enclosed using WRAPPER_OBJECT style is straightforwardjava.lang.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.TypeDeserializer
forProperty(BeanProperty prop)
Method called to create contextual version, to be used for values of given property.JsonTypeInfo.As

Method Detail

forProperty
public TypeDeserializer forProperty(BeanProperty prop)
Description copied from class:TypeDeserializer
Method called to create contextual version, to be used for values of given property. This may be the type itself (as is the case for bean properties), or values contained (forCollection
orMap
valued properties).- Specified by:
forProperty
in classTypeDeserializerBase
-
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

deserializeTypedFromObject
public java.lang.Object deserializeTypedFromObject(JsonParser jp, DeserializationContext ctxt) throws java.io.IOException
Deserializing type id enclosed using WRAPPER_OBJECT style is straightforward- Specified by:
deserializeTypedFromObject
in classTypeDeserializer
- Throws:
java.io.IOException
-
deserializeTypedFromArray
public java.lang.Object deserializeTypedFromArray(JsonParser jp, DeserializationContext ctxt) throws java.io.IOException
Description copied from class:TypeDeserializer
Method called to let this type deserializer handle deserialization of "typed" object, when value itself is serialized as JSON Array (regardless of Java type). Method needs to figure out intended polymorphic type, locateJsonDeserializer
to use, and call it with JSON data to deserializer (which does not contain type information).- Specified by:
deserializeTypedFromArray
in classTypeDeserializer
- Throws:
java.io.IOException
-
deserializeTypedFromScalar
public java.lang.Object deserializeTypedFromScalar(JsonParser jp, DeserializationContext ctxt) throws java.io.IOException
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, locateJsonDeserializer
to use, and call it with JSON data to deserializer (which does not contain type information).- Specified by:
deserializeTypedFromScalar
in classTypeDeserializer
- Throws:
java.io.IOException
-
deserializeTypedFromAny
public java.lang.Object deserializeTypedFromAny(JsonParser jp, DeserializationContext ctxt) throws java.io.IOException
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 classTypeDeserializer
- Throws:
java.io.IOException
