Class RepoSyncJob

java.lang.Object
  org.rhq.enterprise.server.scheduler.jobs.RepoSyncJob

All Implemented Interfaces:

org.quartz.InterruptableJob, org.quartz.Job, org.quartz.StatefulJob

public class RepoSyncJob
extends Object
implements org.quartz.StatefulJob, org.quartz.InterruptableJob

Quartz schedule job that handles synchronizing contents of a repo, including:

• Package Metadata
• Package Bits
• Distribution Tree Metadata
• Distribution Tree Bits

Many of the calls out to the plugin are ultimately made from the ContentProviderManager. The methods in this job do not call that directly, but rather go through EJB methods to get there.

This implements StatefulJob (as opposed to Job) because we do not need nor want this job triggered concurrently. That is, we don't need multiple instances of this job running at the same time.

Much of the functionality in this class was migrated from ContentProviderSyncJob.

Method Detail

execute

public void execute(org.quartz.JobExecutionContext context)
             throws org.quartz.JobExecutionException

Specified by:

execute in interface org.quartz.Job

Throws:

org.quartz.JobExecutionException

createJobDataMap

public static org.quartz.JobDataMap createJobDataMap(org.quartz.JobDetail details,
                                                     org.rhq.core.domain.content.Repo repo)

Creates (if necessary) and populates a job details map to contain the necessary data to perform a repo sync. If there is an existing details map in the provided details object, it will be reused, leaving existing data intact.

Parameters:

details - may not be null

repo - may not be null

Returns:

populated map used to drive a repo sync job; this will be the same map as what exists in the JobDetail.getJobDataMap() call of the details object if that call does not return null

createJobName

public static String createJobName(org.rhq.core.domain.content.Repo repo)

Creates a name to use when scheduling a repo sync job. Calling this method multiple times on the same parameters will always produce the same name.

Parameters:

repo - may not be null

Returns:

name to use to schedule the job; will not be null

createUniqueJobName

public static String createUniqueJobName(org.rhq.core.domain.content.Repo repo)

Performs similar to {#createJobName} except adds uniqueness to the name regardless of the parameters. In other words, calling this method multiple times on the same parameters will always (almost, it's based on system time) produce a unique name.

Parameters:

repo - may not be null

Returns:

name to use to schedule the job; will not be null

interrupt

public void interrupt()
               throws org.quartz.UnableToInterruptJobException

Specified by:

interrupt in interface org.quartz.InterruptableJob

Throws:

org.quartz.UnableToInterruptJobException
