SummaryProvide an interface for creating families of related objects without specifying their concrete classes.Pass a request through a sequence of handlers until one handles it or the chain ends.—
IntentProvide an interface for creating families of related objects without specifying their concrete classes.Pass requests along a chain of handlers until one of them handles the request or the request reaches the end of the chain.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.A request must pass through multiple possible handlers, but the sender should not need to know which handler will process it.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.
  • Requests can become harder to trace because control flows through multiple handlers.
  • A long chain may add overhead if many handlers are checked on every request.
  • It keeps handler logic isolated and easier to extend.
  • 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.Chain of Responsibility is useful for validation pipelines, support routing, approval flows, and any system where requests may be processed by different handlers in sequence.Proxy is useful for lazy loading, access control, caching, logging, and remote service wrappers.
