Overview

Abstract base decoder class.

Defines the basic decoder interface. All decoders must implement:

  • decode(element) - Main decoding method
  • subcontext - Create independent decoder context

Subcontexts

Subcontexts allow creating independent decoder instances for nested structures (like grace notes) that need their own state tracking.
