org.codehaus.jackson.map.deser.MapDeserializer
public class MapDeserializer
Basic serializer that can take Json "Object" structure and
construct a Map
instance, with typed contents.
Note: for untyped content (one indicated by passing Object.class
as the type), UntypedObjectDeserializer
is used instead.
It can also construct Map
s, but not with specific
POJO types, only other containers and primitives/wrappers.

JsonMappingException
public Map<Object,Object> deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException, JsonProcessingException
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.

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

that do not explicitly add support do not expect to get the call.
