Interface NonTransactionalJobHandler<Output>

All Superinterfaces:

JobHandler

public interface NonTransactionalJobHandler<Output>
extends JobHandler

Internal interface for non-transactional job handler implementations. This interface extends from the regular JobHandler, however the 'normal' execute method should not be called, because there's no VariableScope or CommandContext available as no transaction is currently ongoing when the job is executed.

the result of the non-transactional execution

afterExecute

default void afterExecute(JobEntity job,
 String configuration,
 Output output,
