Class NeverRethrowMethodExceptionPolicy

java.lang.Object
com.societegenerale.failover.core.exception.policy.NeverRethrowMethodExceptionPolicy
All Implemented Interfaces:
MethodExceptionPolicy
public class NeverRethrowMethodExceptionPolicy extends Object implements MethodExceptionPolicy
MethodExceptionPolicy that serves recovered data when available, and cascades the original exception only when there is nothing to recover.

Decision logic:

  • If recoveredResult is non-null — return it; the caller is served stale data transparently and the failure is hidden.
  • If recoveredResult is null (store miss, expiry, or store failure) — rethrow the original exception so the caller can react to the outage explicitly.

This is the "best-effort" policy: prefer stale data, but be honest when even that is unavailable.
