Examples of org.eclipse.core.runtime.jobs.ISchedulingRule

org.eclipse.core.runtime.jobs.ISchedulingRule
Scheduling rules are used by jobs to indicate when they need exclusive access to a resource. Scheduling rules can also be applied synchronously to a thread using IJobManager.beginRule(ISchedulingRule) and IJobManager.endRule(ISchedulingRule). The job manager guarantees that no two jobs with conflicting scheduling rules will run concurrently. Multiple rules can be applied to a given thread only if the outer rule explicitly allows the nesting as specified by the contains method.
Clients may implement this interface. @see Job#getRule() @see Job#setRule(ISchedulingRule) @see Job#schedule(long) @see IJobManager#beginRule(ISchedulingRule,org.eclipse.core.runtime.IProgressMonitor) @see IJobManager#endRule(ISchedulingRule) @since 3.0
