Methods

MigrateInstance(MigrationContext)

Migrates an instance with provided context. It may modify context with one of following migration results:

  • ReferenceTypeName != null means that binary content was fully consumed and a reference should be serialized instead. It should contains the referenced object id in ReferenceId;
  • Schema modified and output schema is a class schema, it means that original class binary data was replaced with another class binary data and it should use new object serializer;
  • Schema modified and output schema is the cached serializer schema, it means that original binary content was consumed and object instance created and cached for upcoming deserialization call;
  • Schema modified, but output schema not class or cached object, it means that Reader contains compatible binary data. If reader wasn't modified then it will be reset to initial position.
  • Schema not modified, if Reader modified then it should be re-serialized with original serializer or just reset reader position otherwise.
