Class TypeWrappedDeserializer
java.lang.Object
com.fasterxml.jackson.databind.JsonDeserializer<Object>
com.fasterxml.jackson.databind.deser.impl.TypeWrappedDeserializer
public final class TypeWrappedDeserializer
- extends JsonDeserializer<Object>
Simple deserializer that will call configured type deserializer, passing
in configured data deserializer, and exposing it all as a simple
deserializer.
This is necessary when there is no "parent" deserializer which could handle
details of calling a TypeDeserializer
, most commonly used with
root values.

deserialize
public Object deserialize(JsonParser jp,
DeserializationContext ctxt)
throws IOException,
JsonProcessingException
- Description copied from class:
JsonDeserializer
- Method that can be called to ask implementation to deserialize
JSON content into the value type this serializer handles.
Returned instance is to be constructed by method itself.
Pre-condition for this method is that the parser points to the
first event that is part of value to deserializer (and which
is never JSON 'null' literal, more on this below): for simple
types it may be the only value; and for structured types the
Object start marker.
Post-condition is that the parser will point to the last
event that is part of deserialized value (or in case deserialization
fails, event that was not recognized or usable, which may be
the same event as the one it pointed to upon call).
Note that this method is never called for JSON null literal,
and thus deserializers need (and should) not check for it.
- Specified by:
deserialize
in class JsonDeserializer<Object>
- Parameters:
jp
- Parsed used for reading JSON contentctxt
- Context that can be used to access information about
this deserialization activity.
- Returns:
- Deserializer value
- Throws:
IOException
JsonProcessingException
deserializeWithType
public Object deserializeWithType(JsonParser jp,
DeserializationContext ctxt,
TypeDeserializer typeDeserializer)
throws IOException,
JsonProcessingException
- Description copied from class:
JsonDeserializer
- Deserialization called when type being deserialized is defined to
contain additional type identifier, to allow for correctly
instantiating correct subtype. This can be due to annotation on
type (or its supertype), or due to global settings without
annotations.
Default implementation may work for some types, but ideally subclasses
should not rely on current default implementation.
Implementation is mostly provided to avoid compilation errors with older
code.
- Overrides:
deserializeWithType
in class JsonDeserializer<Object>
typeDeserializer
- Deserializer to use for handling type information
- Throws:
IOException
JsonProcessingException
