Document

A StepExecutionAggregator that can aggregate step executions when they come back from the handler.

Usage

From source file:org.springframework.batch.core.configuration.xml.StepParserStepFactoryBean.java

private void configurePartitionStep(PartitionStep ts) {
    Assert.state(partitioner != null, "A Partitioner must be provided for a partition step");
    configureAbstractStep(ts);//from www. j  av  a  2 s .c o  m

    if (partitionHandler != null) {
        ts.setPartitionHandler(partitionHandler);
    } else {
        TaskExecutorPartitionHandler partitionHandler = new TaskExecutorPartitionHandler();
        partitionHandler.setStep(step);
        if (taskExecutor == null) {
            taskExecutor = new SyncTaskExecutor();
        }
        partitionHandler.setGridSize(gridSize);
        partitionHandler.setTaskExecutor(taskExecutor);
        ts.setPartitionHandler(partitionHandler);
    }

    boolean allowStartIfComplete = this.allowStartIfComplete != null ? this.allowStartIfComplete : false;
