public class UntypedObjectDeserializer extends StdDeserializer<Object> implements ResolvableDeserializer, ContextualDeserializer
Object
(either explicitly, or due to type erasure).
If so, "natural" mapping is used to convert JSON values to their natural
Java object matches: JSON arrays to Java List
s (or, if configured,
Object[]), JSON objects to Map
s, numbers to
Number
s, booleans to Boolean
s and
strings to String
(and nulls to nulls).JsonDeserializer.None

createContextual(DeserializationContext ctxt,
BeanProperty property)
Method called to see if a different (or differently configured) deserializer
is needed to deserialize values of specified property.
|
Object |
deserialize(JsonParser jp,
DeserializationContext ctxt)
Method that can be called to ask implementation to deserialize
JSON content into the value type this serializer handles.

Object |
deserializeWithType(JsonParser jp,
DeserializationContext ctxt,
TypeDeserializer typeDeserializer)
Base implementation that does not assume specific type
inclusion mechanism.
|
protected Object |
mapArray(JsonParser jp,
DeserializationContext ctxt)
Method called to map a JSON Array into a Java value.
|
protected Object[] |
mapArrayToArray(JsonParser jp,
DeserializationContext ctxt)
Method called to map a JSON Array into a Java Object array (Object[]).
|
protected Object |
mapObject(JsonParser jp,
DeserializationContext ctxt)
Method called to map a JSON Object into a Java value.
|

resolve(DeserializationContext ctxt)
We need to implement this method to properly find things to delegate
to: it can not be done earlier since delegated deserializers almost
certainly require access to this instance (at least "List" and "Map" ones)

JsonDeserializer
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.
