SummaryConstruct a complex object step by step so the same construction process can create different representations.—
IntentSeparate the construction of a complex object from its final representation.Separate an algorithm from the object structure it operates on by moving behavior into visitor objects.
Decision factors
ProblemConstructing complex objects directly can make required steps, optional values, and validation 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 more classes or steps to the construction process.
  • Can be overkill for simple objects.
  • Improves clarity when object construction is complex or incremental.
  • Requires updating the visitor interface when new element types are added
  • Can be awkward if the object structure changes often

Integration notesBuilder is most useful when construction must happen in controlled steps and the final object has many optional or ordered parts.Visitor is useful for AST processing, reporting, cart calculations, and exporting object structures to alternate formats.
