Interface BackOff

  • All Known Implementing Classes:
    ExponentialBackOff, FixedBackOff
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
    @FunctionalInterface
public interface BackOff
    Provide a BackOffExecution that indicates the rate at which an operation should be retried.

    Users of this interface are expected to use it like this: 

     BackOffExecution exec = backOff.start();

 // In the operation recovery/retry loop:
 long waitInterval = exec.nextBackOff();
 if (waitInterval == BackOffExecution.STOP) {
     // do not retry operation
 }
 else {
     // sleep, e.g. Thread.sleep(waitInterval)
     // retry operation
 }
 }
    Once the underlying operation has completed successfully, the execution instance can be simply discarded.
