RetryUntilElapsed

public RetryUntilElapsed(long maxElapsedMs,

                         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

getMaxElapsedMillis

public long getMaxElapsedMillis()

Return maximal count of elapsed milliseconds

Returns:

maximal count of elapsed milliseconds

withMaxElapsedMs

public RetryUntilElapsed withMaxElapsedMs(long maxElapsedMs)

Create new retry policy with specified count of elapsed milliseconds

Parameters:

maxElapsedMs - new value of max elapsed milliseconds

Returns:

updated retry policy

withBackoffMs

public RetryUntilElapsed withBackoffMs(long ms)

Create new retry policy with specified backoff duration

Parameters:

ms - new backoff duration

Returns:

new retry policy

withBackoffCeiling

public RetryUntilElapsed withBackoffCeiling(int ceiling)

Create new retry policy with specified backoff ceiling

Parameters:

ceiling - new backoff ceiling

Returns:

new retry policy
