SummaryConstruct a complex object step by step so the same construction process can create different representations.—
IntentSeparate the construction of a complex object from its final representation.Capture and externalize an object's state so it can be restored to a previous point in time.
Decision factors
ProblemConstructing complex objects directly can make required steps, optional values, and validation hard to manage.An object's internal state must be saved and restored later without exposing its implementation details.
Tradeoffs
  • Adds more classes or steps to the construction process.
  • Can be overkill for simple objects.
  • Improves clarity when object construction is complex or incremental.
  • Snapshots can consume memory if many states are stored.
  • Care must be taken to keep mementos immutable and hidden from outside code.

Integration notesBuilder is most useful when construction must happen in controlled steps and the final object has many optional or ordered parts.Memento is useful for undo/redo, checkpoints, draft recovery, and any workflow where state history matters.
