getNullAccessPattern
public AccessPattern getNullAccessPattern()
Description copied from interface:NullValueProvider
Accessor that may be used to determine if and when provider must be called to access null replacement value.- Specified by:

getNullValue
public java.lang.Object getNullValue(DeserializationContext ctxt)
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 interfaceNullValueProvider
