Interface Decorators

  • public interface Decorators
    A Decorator builder which can be used to apply multiple decorators to a Supplier, Callable Function, Runnable, CompletionStage or Consumer.

    Decorators are applied in the order of the builder chain. For example, consider: 
    
 Supplier<String> supplier = Decorators
     .ofSupplier(() -> service.method())
     .withCircuitBreaker(CircuitBreaker.ofDefaults("id"))
     .withRetry(Retry.ofDefaults("id"))
     .withFallback(CallNotPermittedException.class, e -> service.fallbackMethod())
     .decorate();
    This results in the following composition when executing the supplier: 
    Fallback(Retry(CircuitBreaker(Supplier)))
    This means the Supplier is called first, then its result is handled by the CircuitBreaker, then Retry and then Fallback. Each Decorator makes its own determination whether an exception represents a failure.
