Interface MigrationListenerProvider

  • All Known Implementing Classes:
    DefaultMigrationListenerProvider
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
    @FunctionalInterface
@Internal
public interface MigrationListenerProvider
    A provider for MigrationListener instances.

    In order to facilitate the lifecycle management of MigrationListener instances that are provided to a jOOQ Configuration, clients can implement this API. To jOOQ, it is thus irrelevant, if migration listeners are stateful or stateless, local to an execution, or global to an application.

    This is EXPERIMENTAL functionality and subject to change in future jOOQ versions.
