Package org.springframework.util.backoff
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.
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 discarded.
