SummaryProvide an interface for creating families of related objects without specifying their concrete classes.Compose objects into tree structures to represent part-whole hierarchies and let clients work with individual and composite objects through the same interface.—
IntentProvide an interface for creating families of related objects without specifying their concrete classes.Compose objects into tree structures to represent part-whole hierarchies and let clients work with individual and composite objects through the same interface.Separate an algorithm from the object structure it operates on by moving behavior into visitor objects.
Decision factors
ProblemClient code needs to create families of related objects, but hardcoding concrete classes makes the code rigid and hard to swap.A system needs to treat individual objects and groups of objects uniformly, but the hierarchy becomes difficult to manage with separate code paths.You need to perform operations across a set of different object types without stuffing all the logic into the objects themselves.
Tradeoffs
  • Adds an extra abstraction layer.
  • Can overcomplicate simple object creation.
  • Makes family-wide swapping and consistency much easier.
  • Can make the design more abstract and harder to follow.
  • May require careful handling of operations that only apply to some nodes in the tree.
  • Makes recursive tree operations and client code much simpler.
  • Requires updating the visitor interface when new element types are added
  • Can be awkward if the object structure changes often

Integration notesAbstract Factory is especially useful when your app must produce matching sets of related objects for a theme, provider, platform, or pipeline.Composite is useful when a hierarchy of nested objects should expose a common interface, such as files and folders, menus and submenus, org charts, widget trees, or scene graphs.Visitor is useful for AST processing, reporting, cart calculations, and exporting object structures to alternate formats.
