Class OperationTimedPollAlgorithm (2.41.0) 

public class OperationTimedPollAlgorithm extends ExponentialRetryAlgorithm

Operation timed polling algorithm, which uses exponential backoff factor for determining when the next polling operation should be executed. If the polling exceeds the total timeout this algorithm cancels polling.
