Class MapDeserializer
- All Implemented Interfaces:
ResolvableDeserializer
- Direct Known Subclasses:
MapDeserializer
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.

resolve
public void resolve(DeserializationConfig config, DeserializerProvider provider) throws JsonMappingException Method called to finalize setup of this deserializer, after deserializer itself has been registered. This is needed to handle recursive and transitive dependencies.- Specified by:
resolve
in interfaceResolvableDeserializer
- Parameters:
provider
- Provider that has constructed deserializer this method is called on.- Throws:
JsonMappingException
-
getContentType
Description copied from class:ContainerDeserializerBase
Accessor for declared type of contained value elements; either exact type, or one of its supertypes.- Specified by:

getContentDeserializer
Description copied from class:ContainerDeserializerBase

deserialize
public Map<Object,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<Map<Object,
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
-
deserialize
public Map<Object,Object> deserialize(JsonParser jp, DeserializationContext ctxt, Map<Object, Object> result) throws IOException, JsonProcessingExceptionDescription copied from class:JsonDeserializer
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. 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.- Overrides:
deserialize
in classJsonDeserializer<Map<Object,
Object>> - 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<Map<Object,
Object>> - Parameters:
typeDeserializer
- Deserializer to use for handling type information- Throws:
IOException
JsonProcessingException
-
getMapClass
-
getValueType
Description copied from class:StdDeserializer
Exact structured type deserializer handles, if known.Default implementation just returns null.
- Overrides:
