Summary——
IntentEncapsulate a family of algorithms or behaviors behind a common contract so they can be selected and swapped cleanly.Separate an algorithm from the object structure it operates on by moving behavior into visitor objects.
Decision factors
ProblemA system needs to switch between interchangeable behaviors without hardcoding branching logic everywhere.You need to perform operations across a set of different object types without stuffing all the logic into the objects themselves.
Tradeoffs
  • Adds more moving parts than a direct conditional approach
  • Works best when behavior variations are real and likely to grow
  • Requires updating the visitor interface when new element types are added
  • Can be awkward if the object structure changes often

Integration notesStrategies can cross codebases through shared contracts, API selection rules, or runtime configuration.Visitor is useful for AST processing, reporting, cart calculations, and exporting object structures to alternate formats.
