getNullValue

public Object getNullValue(DeserializationContext ctxt)
                    throws JsonMappingException

Description copied from interface: NullValueProvider

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

Specified by:

getNullValue in interface NullValueProvider

Throws:

JsonMappingException
