public interface BackOffPolicy
Strategy interface to control back off between attempts in a single retry operation. Implementations are expected to be thread-safe and should be designed for concurrent access. Configuration for each implementation is also expected to be thread-safe but need not be suitable for high load concurrent access. For each block of retry operations the start(org.springframework.retry.RetryContext) method is called and implementations can return an implementation-specific BackOffContext that can be used to track state through subsequent back off invocations. Each back off process is handled via a call to backOff(org.springframework.retry.backoff.BackOffContext). The RetryTemplate will pass in the corresponding BackOffContext object created by the call to start(org.springframework.retry.RetryContext).
