SummaryProvide an interface for creating families of related objects without specifying their concrete classes.——
IntentProvide an interface for creating families of related objects without specifying their concrete classes.Capture and externalize an object's state so it can be restored to a previous point in time.Provide a surrogate or placeholder for another object to control access to it.
Decision factors
ProblemClient code needs to create families of related objects, but hardcoding concrete classes makes the code rigid and hard to swap.An object's internal state must be saved and restored later without exposing its implementation details.A client needs to interact with an object indirectly because the real object may be expensive, sensitive, or remote.
Tradeoffs
  • Adds an extra abstraction layer.
  • Can overcomplicate simple object creation.
  • Makes family-wide swapping and consistency much easier.
  • Snapshots can consume memory if many states are stored.
  • Care must be taken to keep mementos immutable and hidden from outside code.
  • Adds another layer of indirection
  • Can make the design more complex when the extra control is unnecessary

Integration notesAbstract Factory is especially useful when your app must produce matching sets of related objects for a theme, provider, platform, or pipeline.Memento is useful for undo/redo, checkpoints, draft recovery, and any workflow where state history matters.Proxy is useful for lazy loading, access control, caching, logging, and remote service wrappers.
