SummaryConvert the interface of a class or module into another interface clients expect.Construct a complex object step by step so the same construction process can create different representations.
IntentAllow incompatible interfaces to work together without changing the consuming code.Separate the construction of a complex object from its final representation.
Decision factors
ProblemA client needs to talk to a legacy class or external service whose interface does not match the rest of the codebase.Constructing complex objects directly can make required steps, optional values, and validation hard to manage.
Tradeoffs
  • Adds an extra layer of indirection.
  • Can hide useful vendor-specific capabilities if overused.
  • Keeps integration code isolated from core domain logic.
  • Adds more classes or steps to the construction process.
  • Can be overkill for simple objects.
  • Improves clarity when object construction is complex or incremental.

Integration notesAdapters are useful when exposing a stable boundary over a legacy API, vendor SDK, or payload format mismatch.Builder is most useful when construction must happen in controlled steps and the final object has many optional or ordered parts.
