@InterfaceStability.Experimental @InterfaceAudience.Public public class RetryWithDelayHandler extends Object implements Func1<Tuple2<Integer,Throwable>,Observable<?>>
A class that allows to produce a “retry” delay depending on the number of retry attempts. The number of retries is bounded by a maximum number of attempts.

public RetryWithDelayHandler(int maxAttempts,
Delay retryDelay)
Construct a retry handler that will retry on all errors.
maxAttempts - the maximum number of retries before a CannotRetryException is thrown. It will be capped at Integer.MAX_VALUE - 1retryDelay - the Delay to apply between each retry (can grow, eg. by using ExponentialDelay).public RetryWithDelayHandler(int maxAttempts,

maxAttempts - the maximum number of retries before a CannotRetryException is thrown. It will be capped at Integer.MAX_VALUE - 1retryDelay - the Delay to apply between each retry (can grow, eg. by using ExponentialDelay).errorInterruptingPredicate - a predicate that determine if an error must stop the retry cycle (when true), in which case said error is cascaded down.protected RetryWithDelayHandler(int maxAttempts,
