Interface RetryPolicyTemplate

All Known Implementing Classes:

AbstractPolicyTemplate, AsynchronousRetryTemplate, NoRetryPolicyTemplate, RetryForeverPolicyTemplate, SimpleRetryPolicyTemplate

public interface RetryPolicyTemplate

A RetryPolicyTemplate creates a new RetryPolicy instance each time the retry goes into effect, thereby resetting any state the policy may have (counters, etc.) A RetryNotifier may be set in order to take action upon each retry attempt.

applyPolicy

default <T> org.reactivestreams.Publisher<T> applyPolicy(org.reactivestreams.Publisher<T> publisher,
                                                         Predicate<Throwable> shouldRetry,

Type Parameters:

T - the generic type of the publisher's content

Parameters:

publisher - a publisher with the items which might fail
