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

TypeDeserializer typeDeserializer)
Base implementation that does not assume specific type
inclusion mechanism.

getNullValue()
Method that can be called to determine value to be used for
representing null values (values deserialized when JSON token
is
JsonToken.VALUE_NULL ). |

isCachable()
Method called to see if deserializer instance is cachable and
usable for other properties of same type (type for which instance
was created).

public JsonNode getNullValue()
JsonDeserializer
JsonToken.VALUE_NULL
). Usually this is simply
Java null, but for some types (especially primitives) it may be
necessary to use non-null values.
Note that deserializers are allowed to call this just once and then reuse returned value; that is, method is not guaranteed to be called once for each conversion.
Default implementation simply returns null.

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.
