public ExponentialDelayPolicy(long delayMillis, long maxDelayMillis, double growthFactor)
delayMillis
- -
the minimum delay (in milliseconds) for the first retry
attempt; must be > 0maxDelayMillis
- -
the maximum cap (in milliseconds) applied to the computed
delay; must be >= delayMillisgrowthFactor
- -
the exponential growth factor applied to the previous delay in
order to compute the next delay; must be >= 1.0 with
1.0
resulting in a fixed delayMethod Detail |

numAttempts
- -
the number of previous attempts (including first attempt and
retries); assumed to be >= 1lastDelay
- -
the delay (in milliseconds) returned by the previous call to
this method (i.e., with numAttempts-1
); -1 if
not previously code (i.e., when numAttempts==0
