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 |
deserialize(JsonParser jp,
DeserializationContext ctxt,
Object intoValue)
Alternate deserialization method (compared to the most commonly
used,
JsonDeserializer.deserialize(JsonParser, DeserializationContext) ),
which takes in initialized value instance, to be
configured and/or populated by deserializer. |
Object |
deserializeWithType(JsonParser jp,
DeserializationContext ctxt,
TypeDeserializer typeDeserializer)
Deserialization called when type being deserialized is defined to
contain additional type identifier, to allow for correctly
instantiating correct subtype.

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.

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.

),
which takes in initialized value instance, to be
configured and/or populated by deserializer.
Method is not necessarily used for all supported types; most commonly
it is used
for Collections and Maps.
Default implementation just throws
UnsupportedOperationException
, to indicate that types
that do not explicitly add support do not expect to get the call.
