Interface ResultRetryAlgorithmWithContext<ResponseT> (2.22.0) 

publicinterface ResultRetryAlgorithmWithContext<ResponseT>extendsResultRetryAlgorithm<ResponseT>

A result retry algorithm is responsible for the following operations (based on the response returned by the previous attempt or on the thrown exception):

  1. Accepting a task for retry so another attempt will be made.
  2. Canceling retrying process so the related java.util.concurrent.Future will be canceled.
  3. Creating TimedAttemptSettings for each subsequent retry attempt.

Implementations of this interface receive a RetryingContext that can contain specific RetrySettings and retryable codes that should be used to determine the retry behavior.

Implementations of this interface must be thread-safe.
