Modifier and Type | Field and Description |
---|---|
protected NullValueProvider |
_nuller
Flag that indicates need for special handling; either failing
(throw exception) or skipping
|
protected Boolean |
_unwrapSingle
Specific override for this instance (from proper, or global per-type overrides)
to indicate whether single value may be taken to mean an unwrapped one-element array
or not.

JsonDeserializer<?> |
createContextual(DeserializationContext ctxt,
BeanProperty property)
Method called to see if a different (or differently configured) deserializer
is needed to deserialize values of specified property.
|
T |
deserialize(com.fasterxml.jackson.core.JsonParser p,
DeserializationContext ctxt,
T existing)
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. |
Object |
deserializeWithType(com.fasterxml.jackson.core.JsonParser p,
DeserializationContext ctxt,
TypeDeserializer typeDeserializer)
Base implementation that does not assume specific type
inclusion mechanism.
|
static JsonDeserializer<?> |
forType(Class<?> rawType) |
AccessPattern |
getEmptyAccessPattern()
This method may be called in conjunction with calls to
JsonDeserializer.getEmptyValue(DeserializationContext) , to check whether it needs
to be called just once (static values), or each time empty value is
needed. |
Object |
getEmptyValue(DeserializationContext ctxt)
Method called to determine value to be used for "empty" values
(most commonly when deserializing from empty JSON Strings).
|
protected T |
handleNonArray(com.fasterxml.jackson.core.JsonParser p,
DeserializationContext ctxt) |
protected abstract T |
handleSingleElementUnwrapped(com.fasterxml.jackson.core.JsonParser p,
DeserializationContext ctxt) |
LogicalType |
logicalType()
Method for accessing logical type of values this deserializer produces.
|
Boolean |
supportsUpdate(DeserializationConfig config)
Introspection method that may be called to see whether deserializer supports
update of an existing value (aka "merging") or not.

JsonDeserializer
Boolean.FALSE
if update is not supported at all (immutable values);
Boolean.TRUE
if update should usually work (regular POJOs, for example),
or null
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
deserializer construction if explicit attempt made) if Boolean.FALSE
returned, or inclusion if Boolean.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.

JsonDeserializer
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.

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)
