CORE DEFINITION

Without violating encapsulation, capture an object's internal state and save it outside the object so that it can be restored later. That is, 'save/load'.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Decision snapshot. Before making a major decision, write down your current feelings, the data you rely on, and the expected outcome (save). Review it half a year later (load), which is the best tool for calibrating intuition and avoiding hindsight bias.

anchor

Anchor fast decisions

Without violating encapsulation, capture and externally save the object's state, supporting lossless restoration later; decouple the 'state snapshot' from the object.
