logicalType
Description copied from class:JsonDeserializer
Method for accessing logical type of values this deserializer produces. Typically used for further configuring handling of values, for example, to find which coercions are legal.- Overrides:
logicalType
in classJsonDeserializer<Object>
- Returns:
- Logical type of values this deserializer produces, if known;
null
if not
-
supportsUpdate
Description copied from class:JsonDeserializer
Introspection method that may be called to see whether deserializer supports update of an existing value (aka "merging") or not. Return value should either beBoolean.FALSE
if update is not supported at all (immutable values);Boolean.TRUE
if update should usually work (regular POJOs, for example), ornull
if this is either not known, or may sometimes work.Information gathered is typically used to either prevent merging update for property (either by skipping, if based on global defaults; or by exception during deserialization construction if explicit attempt made) if
Boolean.FALSE
returned, or inclusion ifBoolean.TRUE
is specified. If "unknown" case (null
returned) behavior is to exclude property if global defaults used; or to allow if explicit per-type or property merging is defined.Default implementation returns
null
to allow explicit per-type or per-property attempts.- Overrides:

deserialize
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 or a FIELD_NAME.
The two possible input conditions for structured types result from polymorphism via fields. In the ordinary case, Jackson calls this method when it has encountered an OBJECT_START, and the method implementation must advance to the next token to see the first field name. If the application configures polymorphism via a field, then the object looks like the following.
{ "@class": "class name", ... }
Jackson consumes the two tokens (the @class field name and its value) in order to learn the class and select the deserializer. Thus, the stream is pointing to the FIELD_NAME for the first field after the @class. Thus, if you want your method to work correctly both with and without polymorphism, you must begin your method with:if (p.currentToken() == JsonToken.START_OBJECT) { p.nextToken(); }
This results in the stream pointing to the field name, so that the two conditions align.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.

deserializeWithType
public Object deserializeWithType(JsonParser p, DeserializationContext ctxt, TypeDeserializer typeDeserializer) throws IOException 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>
typeDeserializer
- Deserializer to use for handling type information- Throws:
IOException
-
deserialize
public Object deserialize(JsonParser p, DeserializationContext ctxt, Object intoValue) throws IOException Description 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 (or supported) by all types (it will not work for immutable types, for obvious reasons): most commonly it is used for Collections and Maps. It may be used both with "updating readers" (for POJOs) and when Collections and Maps use "getter as setter".Default implementation just throws
UnsupportedOperationException
, to indicate that types that do not explicitly add support do not necessarily support update-existing-value operation (esp. immutable types)- Overrides:
