Constructor Details

ExponentialBackoff

public ExponentialBackoff()

Initializes a new instance of the ExponentialBackoff class.

ExponentialBackoff

public ExponentialBackoff(int retryCount, Duration minBackoff, Duration maxBackoff, Duration deltaBackoff)

Initializes a new instance of the ExponentialBackoff class with the specified retry settings.

Parameters:

retryCount - The maximum number of retry attempts.

minBackoff - The minimum backoff time

maxBackoff - The maximum backoff time.

deltaBackoff - The value that will be used to calculate a random delta in the exponential delay between retries.

ExponentialBackoff

public ExponentialBackoff(String name, int retryCount, Duration minBackoff, Duration maxBackoff, Duration deltaBackoff)

Initializes a new instance of the ExponentialBackoff class with the specified name and retry settings.

Parameters:

name - The name of the retry strategy.

retryCount - The maximum number of retry attempts.

minBackoff - The minimum backoff time

maxBackoff - The maximum backoff time.

deltaBackoff - The value that will be used to calculate a random delta in the exponential delay between retries.

ExponentialBackoff

public ExponentialBackoff(String name, int retryCount, Duration minBackoff, Duration maxBackoff, Duration deltaBackoff, boolean firstFastRetry)

Initializes a new instance of the ExponentialBackoff class with the specified name, retry settings, and fast retry option.

Parameters:

name - The name of the retry strategy.

retryCount - The maximum number of retry attempts.

minBackoff - The minimum backoff time

maxBackoff - The maximum backoff time.

deltaBackoff - The value that will be used to calculate a random delta in the exponential delay between retries.

firstFastRetry - true to immediately retry in the first attempt; otherwise, false. The subsequent retries will remain subject to the configured retry interval.

Method Details

getShouldRetry

public ShouldRetry getShouldRetry()

Returns the corresponding ShouldRetry delegate.

Returns:

The ShouldRetry delegate.
