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.Represent grammar rules as objects and interpret sentences by evaluating an abstract syntax tree or expression chain.Provide a surrogate or placeholder for another object to control access to it.
Decision factors
ProblemConstructing complex objects directly can make required steps, optional values, and validation hard to manage.You need to define a small language or expression grammar and evaluate it consistently across the application.A client needs to interact with an object indirectly because the real object may be expensive, sensitive, or remote.
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.
  • Can become complex if the grammar grows too large.
  • Best suited to small, well-defined languages or expression sets.
  • Adds another layer of indirection
  • Can make the design more complex when the extra control is unnecessary

Integration notesBuilder is most useful when construction must happen in controlled steps and the final object has many optional or ordered parts.Interpreter is useful for calculators, rule engines, simple DSLs, and command parsing systems where a structured grammar must be evaluated.Proxy is useful for lazy loading, access control, caching, logging, and remote service wrappers.
