Summary——
IntentDefine a creation method behind a common interface so specialized creators can decide which concrete product to instantiate without changing the surrounding workflow.Provide a surrogate or placeholder for another object to control access to it.
Decision factors
ProblemA workflow needs to create one of several related concrete objects, but constructing them directly in client code spreads creation logic and tightly couples the caller to specific implementations.A client needs to interact with an object indirectly because the real object may be expensive, sensitive, or remote.
Tradeoffs
  • Adds extra indirection and more types compared with direct construction
  • Can feel unnecessarily abstract when object creation is simple and unlikely to vary
  • Adds another layer of indirection
  • Can make the design more complex when the extra control is unnecessary

Integration notesFactory Method is useful when framework hooks, integrations, or environment-specific workflows need to create interchangeable implementations behind a stable contract.Proxy is useful for lazy loading, access control, caching, logging, and remote service wrappers.
