Summary———
IntentRepresent grammar rules as objects and interpret sentences by evaluating an abstract syntax tree or expression chain.Define an object that encapsulates communication between a set of objects, keeping them from referring to each other directly.Specify the kinds of objects to create using a prototypical instance, and create new objects by cloning that prototype.
Decision factors
ProblemYou need to define a small language or expression grammar and evaluate it consistently across the application.Multiple objects need to coordinate behavior, but direct references between them create tight coupling and complex dependencies.Creating new objects from scratch can be expensive or repetitive when the system needs many similar variants.
Tradeoffs
  • Can become complex if the grammar grows too large.
  • Best suited to small, well-defined languages or expression sets.
  • The mediator can become large and complex if it takes on too much coordination logic.
  • Centralizing behavior can make the mediator a single point of failure if it is poorly designed.
  • Can be difficult if the object graph contains deep references that need custom clone behavior
  • May require careful handling of mutable state to avoid shared-reference bugs

Integration notesInterpreter is useful for calculators, rule engines, simple DSLs, and command parsing systems where a structured grammar must be evaluated.Mediator is useful for chat systems, form coordination, workflow orchestration, and any domain where many components must collaborate without knowing about each other.Prototype is useful when object creation is expensive, when many near-identical objects are needed, or when cloning preconfigured templates is simpler than rebuilding them.
