Examples of org.springframework.batch.core.Step

org.springframework.batch.core.Step
Batch domain interface representing the configuration of a step. As with the {@link Job}, a {@link Step} is meant toexplicitly represent the configuration of a step by a developer, but also the ability to execute the step. @author Dave Syer
