public Object getNullValue(DeserializationContext ctxt) throws JsonMappingException

Implements com.fasterxml.jackson.databind.deser.NullValueProvider.getNullValue.

Doc from com.fasterxml.jackson.databind.deser.NullValueProvider.getNullValue.

Method called to possibly convert incoming `null` token (read via underlying streaming input source) into other value of type accessor supports. May return `null`, or value compatible with type binding.

Note

if getNullAccessPattern() returns `ALWAYS_NULL` or `CONSTANT`, this method WILL NOT use provided `ctxt` and it may thus be passed as `null`.
