Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Bidirectional codec over Ruby objects.

Wraps a pair of dump/load transforms that convert between domain objects and a JSON-compatible Ruby structure (hashes, arrays, primitives). The outer layer that converts the structure to/from a JSON string is handled by callers as needed.
