Examples of javax.batch.operations.JobOperator

javax.batch.operations.JobOperator
JobOperator provides the interface for operating on batch jobs. Through the JobOperator a program can start, stop, and restart jobs. It can additionally inspect job history, to discover what jobs are currently running and what jobs have previously run. The JobOperator interface imposes no security constraints. However, the implementer is free to limit JobOperator methods with a security scheme of its choice. The implementer should terminate any method that is limited by the security scheme with a JobSecurityException.

    private Map<String, Object> handleJob(JobExecution je, ColumnFormatter columnFormatter)
        throws  SecurityException {
        Map<String, Object> jobInfo = new HashMap<>();


        String[] cfData = new String[getOutputHeaders().length];
        JobOperator jobOperator = BatchRuntime.getJobOperator();
        for (int index = 0; index < getOutputHeaders().length; index++) {
            Object data = null;
            switch (getOutputHeaders()[index]) {
                case JOB_NAME:
                    data = jobOperator.getJobInstance(je.getInstanceId()).getJobName();
                    break;
                case INSTANCE_COUNT:
                    data = jobOperator.getJobInstanceCount(jobOperator.getJobInstance(je.getInstanceId()).getJobName());
                    break;
                case INSTANCE_ID:
