|
Object |
getEmptyValue(DeserializationContext ctxt)
Method called to determine value to be used for "empty" values
(most commonly when deserializing from empty JSON Strings).

boolean |
isCachable()
Because of costs associated with constructing Enum resolvers,
let's cache instances by default.
|
LogicalType |
logicalType()
Method for accessing logical type of values this deserializer produces.
|
void |
resolve(DeserializationContext ctxt)
Method called after deserializer instance has been constructed
(and registered as necessary by provider objects),
but before it has returned it to the caller.

JsonDeserializer.getNullValue(com.fasterxml.jackson.databind.DeserializationContext)
(which in turn
is usually simply Java null), but it can be overridden
for specific types. Or, if type should never be converted from empty
String, method can also throw an exception.
This method may be called once, or multiple times, depending on what
JsonDeserializer.getEmptyAccessPattern()
returns.
Default implementation simply calls JsonDeserializer.getNullValue(com.fasterxml.jackson.databind.DeserializationContext)
and
returns value.

public EnumMap<?,?> deserialize(JsonParser p, DeserializationContext ctxt) throws IOException
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 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.

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)
