Interface StaleStateMapper

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 StaleStateMapper

Maps a stale-state failure reported while checking a JDBC batch result.

A mapper is associated with one row as it is added to a GroupedBatch. If row-count verification for that row throws a StaleStateException, the batch invokes this mapper before propagating the failure.

Returning null means the stale-state condition was handled and should not be propagated. Returning an exception means the batch should throw that exception instead of the original stale-state exception. Implementations may return the supplied exception unchanged when no translation is needed.
