Examples of org.springframework.retry.RetryState

org.springframework.retry.RetryState
Stateful retry is characterised by having to recognise the items that are being processed, so this interface is used primarily to provide a cache key in between failed attempts. It also provides a hints to the {@link RetryOperations} for optimisations to do with avoidable cache hits andswitching to stateless retry if a rollback is not needed. @author Dave Syer
