Doc from tools.jackson.databind.deser.DeserializationProblemHandler.handleMissingInstantiator.

Method called when instance creation for a type fails due to lack of an instantiator. Method is called before actual deserialization from input is attempted, so handler may do one of following things:

  • Indicate it does not know what to do by returning NOT_HANDLED
  • Throw a IOException to indicate specific fail message (instead of standard exception caller would throw
  • Handle content to match (by consuming or skipping it), and return actual instantiated value (of type targetType) to use as replacement; value may be `null` as well as expected target type.
