SummaryWrap an object with other objects that implement the same contract so responsibilities can be layered dynamically.—
IntentWrap an object with other objects that implement the same contract so responsibilities can be layered dynamically.Specify the kinds of objects to create using a prototypical instance, and create new objects by cloning that prototype.
Decision factors
ProblemA system needs to add optional behaviors to an object without creating many subclasses for every feature combination.Creating new objects from scratch can be expensive or repetitive when the system needs many similar variants.
Tradeoffs
  • Can introduce many small wrapper classes that are harder to trace in debugging.
  • Ordering of decorators matters, so composition needs to be deliberate.
  • Keeps responsibilities modular and easy to combine.
  • 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 notesDecorators work well for cross-cutting concerns such as logging, retry, caching, compression, and telemetry because each layer keeps the same interface while adding one concern.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.
