                                      int maxRetries)

Parameters:

baseSleepTimeMs - initial amount of time to wait between retries

maxSleepTimeMs - maximum amount of time to wait between retries

maxRetries - maximum number of times to retry

Method Detail

allowRetry

public boolean allowRetry(int retryCount,
                          long elapsedTimeMs,
                          RetrySleeper sleeper)

Description copied from interface: RetryPolicy

Called when an operation has failed for some reason. This method should return true to make another attempt.

Specified by:

allowRetry in interface RetryPolicy

Parameters:

retryCount - the number of times retried so far (0 the first time)

elapsedTimeMs - the elapsed time in ms since the operation was attempted

sleeper - use this to sleep - DO NOT call Thread.sleep

Returns:

true/false
