Class DefaultBackoffPolicy

  • All Implemented Interfaces:
    BackoffPolicy

    public final class DefaultBackoffPolicy
    extends Object
    implements BackoffPolicy
    A BackoffPolicy that does an 'exponential' backoff. So each next attempt, the calculated delay is increased and randomized (so the next value can be smaller than the previous, but overall they will increase).
    • Constructor Detail

      • DefaultBackoffPolicy

        public DefaultBackoffPolicy()
        Creates an ExponentialBackoffPolicy with 100 nanoseconds as minimal delay and 100 milliseconds as maximum delay.
      • DefaultBackoffPolicy

        public DefaultBackoffPolicy​(long minDelayNs)
        Creates an ExponentialBackoffPolicy with given maximum delay.
        Parameters:
        minDelayNs - the minimum delay in nanoseconds to wait. If a negative or zero value provided, it will be interpreted that no external minimal value is needed.
        Throws:
        NullPointerException - if unit is null.

      • delayUninterruptible

        public void delayUninterruptible​(int attempt)
        Description copied from interface: BackoffPolicy
        Delays the calling Thread without being interrupted.

        The implementation is free to make this a no-op call.

        Specified by:
        delayUninterruptible in interface BackoffPolicy
