Constructor Detail

ExponentialBackoffRetryStrategy

public ExponentialBackoffRetryStrategy()

Initializes a new instance of the ExponentialBackoffRetryStrategy class.

ExponentialBackoffRetryStrategy

public ExponentialBackoffRetryStrategy(int retryCount,
                                       int minBackoff,
                                       int maxBackoff,
                                       int deltaBackoff)

Initializes a new instance of the ExponentialBackoffRetryStrategy class.

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.

ExponentialBackoffRetryStrategy

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

Initializes a new instance of the ExponentialBackoffRetryStrategy class.

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 Detail

shouldRetry

public boolean shouldRetry(int retryCount,
                           okhttp3.Response response)

Returns if a request should be retried based on the retry count, current response, and the current strategy.

Specified by:

shouldRetry in class RetryStrategy

Parameters:

retryCount - The current retry attempt count.

response - The exception that caused the retry conditions to occur.

Returns:

true if the request should be retried; false otherwise.
