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<JsonNode>
jp - Parsed used for reading Json content
ctxt - Context that can be used to access information about this deserialization activity.

                                     JsonNode oldValue,
                                     JsonNode newValue)
                              throws JsonProcessingException
Method called when there is a duplicate value for a field. By default we don't care, and the last value is used. Can be overridden to provide alternate handling, such as throwing an exception, or choosing different strategy for combining values or choosing which one to keep.

fieldName - Name of the field for which duplicate value was found
objectNode - Object node that contains values
oldValue - Value that existed for the object node before newValue was added
newValue - Newly added value just added to the object node
