public T getNullValue(DeserializationContext ctxt)

Overrides tools.jackson.databind.ValueDeserializer.getNullValue.

Implements tools.jackson.databind.deser.NullValueProvider.getNullValue.

Doc from tools.jackson.databind.ValueDeserializer.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). 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 getNullAccessPattern() returns.

Default implementation simply returns null.
