We provide a hierarchy of errors which allow to clearly identify the problem if something went wrong:
  • FLError
    • FLSerializationError
      • FLNotSerializable
      • FLObjectNotFound
      • FLObsolete
    • FLMaterializationError
      • FLBadSignature
      • FLBadVersion
      • FLClassNotFound
      • FLGlobalNotFound
      • FLMethodChanged
      • FLMethodNotFound
As most classes of Fuel, they have class comments that give an idea their meanings:
FLError
I represent an error produced during Fuel operation.
FLSerializationError
I represent an error happened during serialization.
FLNotSerializable
I represent an error which may happen while tracing in the graph an object that is forbidden of being serialized.
FLObjectNotFound
I represent an error which may happen during serialization, when trying to encode on the stream a reference to an object that should be encoded before, but it is not. This usually happens when the graph changes during serialization. Another possible cause is a bug in the analysis step of serialization.
FLObsolete
I am an error produced during serialization, signaled when trying to serialize an obsolete class as global. It is a prevention, because such class is likely to be absent during materialization.
FLMaterializationError
I represent an error happened during materialization.
FLBadSignature
I represent an error produced during materialization when the serialized signature doesn't match the materializer's signature (accessible via FLMaterializer>>signature). A signature is a byte prefix that should prefix a well-serialized stream.
FLBadVersion
I represent an error produced during materialization when the serialized version doesn't match the materializer's version (accessible via FLMaterializer>>version). A version is encoded in 16 bits and is encoded heading the serialized stream, after the signature.
FLClassNotFound
I represent an error produced during materialization when a serialized class or trait name doesn't exist.
FLGlobalNotFound
I represent an error produced during materialization when a serialized global name doesn't exist (at Smalltalk globals).
FLMethodChanged
I represent an error produced during materialization when is detected a change in the bytecodes of a method serialized as global. This error was born when testing the materialization of a BlockClosure defined in a method that changed. The test produced a VM crash.
FLMethodNotFound
I represent an error produced during materialization when a serialized method in a class or trait name doesn't exist (at Smalltalk globals).
