Interface BatchedResultChecker

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@Incubating
@FunctionalInterface
public interface BatchedResultChecker

Checks the result for one row in a JDBC batch.

The checker gives higher-level mutation code a row-specific hook for handling optimistic-lock and stale-state outcomes after JDBC batch execution. It is associated with a row when that row is added to a SingleStatementBatch.

Implementations return true when the observed outcome is acceptable and false when the batch should keep treating the row as a stale-state failure. A thrown SQLException is converted by the owning batch.

Since:

8.0
