- Direct Known Subclasses:
UntypedObjectDeserializer
Deserializer implementation that is used if it is necessary to bind content of
"unknown" type; something declared as basic
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).- Since:
- 1.9 (moved from higher-level package)

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 classJsonDeserializer<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:StdDeserializer
Base implementation that does not assume specific type inclusion mechanism. Sub-classes are expected to override this method if they are to handle type information.- Overrides:
deserializeWithType
in classStdDeserializer<Object>
- Parameters:
typeDeserializer
- Deserializer to use for handling type information- Throws:
IOException
JsonProcessingException
-
