Method Details

of

public static <T> CircuitBreakerTransformer<T> of(io.github.resilience4j.circuitbreaker.CircuitBreaker circuitBreaker)

Create a new transformer that can be applied to the Promise.transform(Function) method. The Promised value will pass through the circuitbreaker, potentially causing it to open if the thresholds for the circuit breaker are exceeded.

Type Parameters:

T - the type of object

Parameters:

circuitBreaker - the circuit breaker to use

Returns:

the transformer

recover

public CircuitBreakerTransformer<T> recover(ratpack.func.Function<java.lang.Throwable,? extends T> recoverer)

Set a recovery function that will execute when the circuit breaker is open.

Parameters:

recoverer - the recovery function

Returns:

the transformer

apply

public ratpack.exec.Upstream<T> apply(ratpack.exec.Upstream<? extends T> upstream) throws java.lang.Exception

Throws:

java.lang.Exception
