deserializeWithType(com.fasterxml.jackson.core.JsonParser p,
DeserializationContext ctxt,
TypeDeserializer typeDeserializer)
Base implementation that does not assume specific type
inclusion mechanism.

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).
|
java.lang.Boolean |
supportsUpdate(DeserializationConfig config)
Introspection method that may be called to see whether deserializer supports
update of an existing value (aka "merging") or not.

updateArray(com.fasterxml.jackson.core.JsonParser p,
DeserializationContext ctxt,
ArrayNode node)
Alternate deserialization method that is to update existing
ObjectNode
if possible. |

public boolean isCachable()
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.

in class JsonDeserializer<T extends JsonNode>
public java.lang.Boolean supportsUpdate(DeserializationConfig config)
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
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.
