Method Detail

resolveInheritance

public static void resolveInheritance(Job job,
                                      ClassLoader classLoader,
                                      List<Job> loadedJobs,
                                      JobXmlResolver jobXmlResolver)
                               throws javax.batch.operations.JobStartException

The main entry point to resolve JSL inheritance for a job, including any inheritance in its sub-elements.

Parameters:

job - the job to resolve its JSL inheritance

classLoader - the class loader to use for loading jobs and resources

loadedJobs - list of already loaded jobs to avoid reloading them while resolving inheritance

jobXmlResolver - job xml resolver, typically obtained from org.jberet.spi.BatchEnvironment#getJobXmlResolver()

Throws:

javax.batch.operations.JobStartException - if failed to resolve the job's inheritance

merge

public void merge()
           throws javax.batch.operations.JobStartException

Performs the merge, and if the parent job has its own parent, it is also resolved. This method does not process JSL inheritance in the job's sub-element, which is done in resolveInheritance(Job, ClassLoader, List, JobXmlResolver)

Throws:

javax.batch.operations.JobStartException - if failed due to cyclic inheritance or other errors
