Class FlowJob

java.lang.Object

org.springframework.batch.core.job.AbstractJob

org.springframework.batch.core.job.flow.FlowJob

All Implemented Interfaces:

Job, StepLocator, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.InitializingBean

public class FlowJob
extends AbstractJob

Implementation of the Job interface that allows for complex flows of steps, rather than requiring sequential execution. In general, this job implementation was designed to be used behind a parser, allowing for a namespace to abstract away details.

Since:

2.0

Constructor Detail

FlowJob

public FlowJob()

Create a FlowJob with null name and no flow (invalid state).

FlowJob

public FlowJob(String name)

Create a FlowJob with provided name and no flow (invalid state).

Method Detail

setFlow

public void setFlow(Flow flow)

Public setter for the flow.

Parameters:

flow - the flow to set

getStep

public Step getStep(String stepName)

Retrieve the step with the given name. If there is no Step with the given name, then return null.

Specified by:

getStep in interface StepLocator

Specified by:

getStep in class AbstractJob

Returns:

the Step

getStepNames

public Collection<String> getStepNames()

Retrieve the step names.

Specified by:

getStepNames in interface StepLocator

Specified by:

getStepNames in class AbstractJob

Returns:

the step names

doExecute

protected void doExecute(JobExecution execution)
                  throws JobExecutionException

Description copied from class: AbstractJob

Extension point for subclasses allowing them to concentrate on processing logic and ignore listeners and repository calls. Implementations usually are concerned with the ordering of steps, and delegate actual step processing to AbstractJob.handleStep(Step, JobExecution).

Specified by:

doExecute in class AbstractJob

Parameters:

execution - the current JobExecution

Throws:

JobExecutionException - to signal a fatal batch framework error (not a business or validation exception)
