Class PartitionStep

java.lang.Object

org.springframework.batch.core.step.AbstractStep

org.springframework.batch.core.partition.support.PartitionStep

org.springframework.batch.core.jsr.step.PartitionStep

All Implemented Interfaces:

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

public class PartitionStep
extends PartitionStep
implements StepLocator

An extension of the PartitionStep that provides additional semantics required by JSR-352. Specifically, this implementation adds the required lifecycle calls to the PartitionReducer if it is used.

Method Detail

setPartitionReducer

public void setPartitionReducer(javax.batch.api.partition.PartitionReducer reducer)

doExecute

protected void doExecute(StepExecution stepExecution)
                  throws java.lang.Exception

Delegate execution to the PartitionHandler provided. The StepExecution passed in here becomes the parent or master execution for the partition, summarizing the status on exit of the logical grouping of work carried out by the PartitionHandler. The individual step executions and their input parameters (through ExecutionContext) for the partition elements are provided by the StepExecutionSplitter.

Overrides:

doExecute in class PartitionStep

Parameters:

stepExecution - the master step execution for the partition

Throws:

java.lang.Exception
