 /**
  * This file contains code to generate serialization/deserialization logic for
  * summaries based on an "IDL" description of the summary format (written in
  * stylized Dart).
  *
  * For each class in the "IDL" input, two corresponding classes are generated:
  * - A class with the same name which represents deserialized summary data in
  *   memory.  This class has read-only semantics.
  * - A "builder" class which can be used to generate serialized summary data.
  *   This class has write-only semantics.
  *
- * Each of the "builder" classes has a single `finish` method which finalizes
- * the entity being built and returns it as an [Object].  This object should
- * only be passed to other builders (or to [BuilderContext.getBuffer]);
- * otherwise the client should treat it as opaque, since it exposes
- * implementation details of the underlying summary infrastructure.
+ * Each of the "builder" classes has a single `finish` method which writes
+ * the entity being built into the given FlatBuffer and returns the `Offset`
+ * reference to it.
