Detailed Description

Interface for snapshotting and restoring BlockAccessor states.

This header declares the IDBMemento interface, which provides a generic API for:

• taking snapshots of a BlockAccessor (parameter blocks),
• restoring one or more steps back in the snapshot history,
• inspecting stored snapshots.

Concrete implementations (e.g. DBMemento) decide how snapshots are stored in memory (stack, ring buffer, etc.).
