public class JsonNodeDeserializer extends StdDeserializer<T>
JsonNode from any
JSON content, using appropriate JsonNode type.
Rewritten in Jackson 2.13 to avoid recursion and allow handling of very deeply nested structures.

Implementation that will produce types of any JSON nodes; not just one
deserializer is registered to handle (in case of more specialized handler).

Base implementation that does not assume specific type
inclusion mechanism.

getAbsentValue(DeserializationContext ctxt)
Overridden variant to ensure that absent values are NOT coerced into
NullNodes, unlike incoming null values. |

getDeserializer(Class<?> nodeClass)
Factory method for accessing deserializer for specific node type
|
JsonNode |
getNullValue(DeserializationContext ctxt)
Method that can be called to determine value to be used for
representing null values (values deserialized when JSON token
is
JsonToken.VALUE_NULL). |
boolean |
isCachable()
Method called to see if deserializer instance is cachable and
usable for other properties of same type (type for which instance
was created).
|
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.
|

updateObject(JsonParser p,
DeserializationContext ctxt,
ObjectNode node,
com.fasterxml.jackson.databind.deser.std.BaseNodeDeserializer.ContainerStack stack)
Alternate deserialization method that is to update existing

public static JsonDeserializer<? extends JsonNode> getDeserializer(Class<?> nodeClass)
public JsonNode getNullValue(DeserializationContext ctxt)
JsonDeserializerJsonToken.VALUE_NULL). Usually this is simply
Java null, but for some types (especially primitives) it may be
necessary to use non-null values.
This method may be called once, or multiple times, depending on what
JsonDeserializer.getNullAccessPattern() returns.
Default implementation simply returns null.

JsonDeserializer
Note that cached instances are still resolved on per-property basis,
if instance implements ResolvableDeserializer:
cached instance is just as the base. This means that in most cases it is safe to
cache instances; however, it only makes sense to cache instances
if instantiation is expensive, or if instances are heavy-weight.
Default implementation returns false, to indicate that no caching is done.
isCachable in class JsonDeserializer<T extends JsonNode>public Boolean supportsUpdate(DeserializationConfig config)
JsonDeserializerBoolean.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
deserialization 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.
