Summary——
IntentRepresent grammar rules as objects and interpret sentences by evaluating an abstract syntax tree or expression chain.Define the skeleton of an algorithm in a base class and let subclasses override selected steps without changing the overall structure.
Decision factors
ProblemYou need to define a small language or expression grammar and evaluate it consistently across the application.Several classes share the same algorithm structure, but some steps need to vary between implementations.
Tradeoffs
  • Can become complex if the grammar grows too large.
  • Best suited to small, well-defined languages or expression sets.
  • Relies on inheritance, which can be less flexible than composition in some designs
  • May create a deep class hierarchy if many variations are needed

Integration notesInterpreter is useful for calculators, rule engines, simple DSLs, and command parsing systems where a structured grammar must be evaluated.Template Method is useful when you have repeated workflows with a common sequence of steps, such as processing orders, generating reports, and importing data.
