      • getAttemptCount

        public int getAttemptCount()
        Description copied from interface: RetryPolicy
        How many retries have been performed. If no retries have been performed, 0 is returned.

        getAttemptCount in interface RetryPolicy
        Returns:
        number of retries performed

      • attempt

        public boolean attempt()
        Description copied from interface: RetryPolicy
        Waits until it is time to perform the next retry, then returns. Returns false if no further retries should be performed. The first call to this method should never delay the caller, this allow users of the policy to use it in the context of a while-loop.
        Specified by:
        attempt in interface RetryPolicy
        Returns:
        whether another retry should be performed

      • computeNextWaitTime

        protected abstract java.time.Duration computeNextWaitTime()
        Returns:
        how long to wait before the next retry
