SummaryEncapsulate a request as an object so it can be invoked, queued, logged, or undone independently of the receiver that performs the work.—
IntentEncapsulate a request as an object so it can be invoked, queued, logged, or undone independently of the receiver that performs the work.Represent grammar rules as objects and interpret sentences by evaluating an abstract syntax tree or expression chain.
Decision factors
ProblemA system needs to trigger actions without tightly coupling the code that requests an operation to the code that performs it, and it may also need queuing, history, or undo support.You need to define a small language or expression grammar and evaluate it consistently across the application.
Tradeoffs
  • Introduces extra classes or objects for each action.
  • Can feel heavier than direct method calls when the workflow is simple.
  • Makes requests more flexible, loggable, and replayable.
  • Can become complex if the grammar grows too large.
  • Best suited to small, well-defined languages or expression sets.

Integration notesCommands work well for UI actions, background jobs, workflow steps, and undoable operations because invokers can trigger commands without depending on receiver details.Interpreter is useful for calculators, rule engines, simple DSLs, and command parsing systems where a structured grammar must be evaluated.
