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.Allow an object to alter its behavior when its internal state changes by delegating state-specific behavior to separate state objects.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.An object behaves differently depending on its internal state, and conditional logic is becoming hard to manage.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 introduce many small classes if the state graph is large
  • State transitions may become harder to trace if spread across multiple classes
  • 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.State is useful for workflows, media players, order lifecycles, and any domain where behavior changes as the object moves through a lifecycle.Visitor is useful for AST processing, reporting, cart calculations, and exporting object structures to alternate formats.
