RetryNTimes

                   long backoffMs,
                   int backoffCeiling)

Method Detail

nextRetryMs

public long nextRetryMs(int retryCount,
                        long elapsedTimeMs)

Description copied from interface: RetryPolicy

Called when an operation is failed for some reason to determine if it should be retried. And if so, returns the delay to make the next retry attempt after

Parameters:

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

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

Returns:

delay for the next retry

• Positive number N - operation must be retried in N milliseconds
• Zero : operation must be retried immediately
• Negative number : retry is not allowed, operation must be failed

getMaxRetries

public int getMaxRetries()

Return maximal count of retries

Returns:

maximal count of retries

withMaxRetries

public RetryNTimes withMaxRetries(int maxRetries)

Create new retry policy with specified max retries count

Parameters:

maxRetries - new value of max count of retries

Returns:

updated retry policy

withBackoffMs

public RetryNTimes withBackoffMs(long ms)

Create new retry policy with specified backoff duration

Parameters:

ms - new backoff duration in milliseconds

Returns:

updated retry policy

withBackoffCeiling

public RetryNTimes withBackoffCeiling(int ceiling)

Create new retry policy with specified backoff ceiling

Parameters:

ceiling - new backoff ceiling

Returns:

updated retry policy
