## Description

TPropertyNotFoundEvent is the prototype for the TReader.OnPropertyNotFound event. Reader is the sender of the event, Instance is the instance that is being streamed. PropInfo is a pointer to the RTTI information for the property being read. Handled should be set to True if the handler redirected the unknown property successfully, and Skip should be set to True if the value should be skipped. IsPath determines whether the property refers to a sub-property.
