FlowStep (Spring Batch 4.1.4.RELEASE API)

java.lang.Object
- org.springframework.batch.core.step.AbstractStep
- - org.springframework.batch.core.job.flow.FlowStep

All Implemented Interfaces:
Step, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.InitializingBean
```
public class FlowStep
extends AbstractStep
```
A Step implementation that delegates to a Flow. Useful for logical grouping of steps, and especially for partitioning with multiple steps per execution. If the flow has steps then when the FlowStep executes, all steps including the parent FlowStep will have executions in the JobRepository (one for the parent and one each for the flow steps).
