SummaryProvide an interface for creating families of related objects without specifying their concrete classes.Separate an abstraction from its implementation so the two can vary independently.—
IntentProvide an interface for creating families of related objects without specifying their concrete classes.Decouple abstractions from implementations so they can evolve independently.Specify the kinds of objects to create using a prototypical instance, and create new objects by cloning that prototype.
Decision factors
ProblemClient code needs to create families of related objects, but hardcoding concrete classes makes the code rigid and hard to swap.When an abstraction is tightly coupled to its implementation, changing one side forces changes in the other and makes the system harder to evolve.Creating new objects from scratch can be expensive or repetitive when the system needs many similar variants.
Tradeoffs
  • Adds an extra abstraction layer.
  • Can overcomplicate simple object creation.
  • Makes family-wide swapping and consistency much easier.
  • Adds an extra layer of indirection.
  • Can increase the number of moving parts.
  • Makes abstractions and implementations easier to evolve independently.
  • Can be difficult if the object graph contains deep references that need custom clone behavior
  • May require careful handling of mutable state to avoid shared-reference bugs

Integration notesAbstract Factory is especially useful when your app must produce matching sets of related objects for a theme, provider, platform, or pipeline.Bridge is useful when you want one stable abstraction while swapping implementations for providers, environments, or device targets.Prototype is useful when object creation is expensive, when many near-identical objects are needed, or when cloning preconfigured templates is simpler than rebuilding them.
