What is the correct way to check if the current Thread "owns" a IScedulingRule?

[laeubi]

Assume i have the following

ISchedulingRule rule = ResourcesPlugin.getWorkspace().getRoot();

now I want to check if the current thread "owns" the rule already, similar to

https://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#holdsLock%28java.lang.Object%29

I poked around a bit but didn't finde something in this regards, there is Job.getJobManager().currentRule() but from the description it will give different results depending on if its called from a Job and also depends on nesting rules...

You can try something like

try {
  jobManager.beginRule(rule, monitor);
  return true;
} catch (IllegalArgumentException ex) {
  return false;
} finally {
  manager.endRule(rule);
}

Or, with the currentRule, you can know if your operation can be scheduled or not in that thread calling by getting the currentRule and calling !currentRule.isConflicting(myRule) || currentRule.contains(myRule)
