Interface MissingFieldHandler

All Known Subinterfaces:
JsonReader.MissingFieldHandler
public interface MissingFieldHandler
Implement this interface to react to fields missing when reading an object. This handler will be called after all deserialization has occurred to allow all references to be resolved.

Register your handler using ReadOptionsBuilder.missingFieldHandler(MissingFieldHandler).
