Class JobOperatorService

java.lang.Object

org.jberet.operations.AbstractJobOperator

org.wildfly.extension.batch.jberet.deployment.JobOperatorService

All Implemented Interfaces:

javax.batch.operations.JobOperator, org.jboss.msc.Service, org.jboss.msc.service.Service<javax.batch.operations.JobOperator>, org.jboss.msc.value.Value<javax.batch.operations.JobOperator>

public class JobOperatorService
extends org.jberet.operations.AbstractJobOperator
implements javax.batch.operations.JobOperator, org.jboss.msc.service.Service<javax.batch.operations.JobOperator>

A delegating job operator to interact with the batch environment on deployments.

Note that for each method the job name, or derived job name, must exist for the deployment. The allowed job names and job XML descriptor are determined at deployment time.

This implementation does change some of the API's contracts however it's only intended to be used by management resources and operations. Limits the interaction with the jobs to the scope of the deployments jobs. Any behavioral change will be documented.

Parameters:

supplier - the supplier for the value

defaultValue - the default value if a NoSuchJobException is thrown

Returns:

the value from the supplier or the default value if a NoSuchJobException was thrown
