How to access Subsequences/callees properties?

[km9394]

Is there any method to access properties or variable directly from caller to callee, without using parameter and global variable?

Hi km9394,

Yes, use the Lookup string RunState.caller.RunState..

For each level of call you would add 'RunState.Caller.'

If you run a SequenceFile using the process model and you were a step inside the MainSequence of your SequenceFile.
The order of the properties would be
RunState. - this would be for the SequenceFile MainSequence.
RunState.Caller.RunState. - this would be for the ProcessModel.

Therefore if your step wanted to get the name of the Step of the caller then the expression would be Locals.CallerName = NameOf(RunState.Caller.RunState.Step) would return "MainSequence Callback"

Hope this helps

May be my question is quite misleading. If I want to get the property of a subsequence that the current sequence will call (Callee, not caller), is it possible?

[RayFarmer]

Hi km9394,

Yes, RunState.SequenceFile.Data.Seq[0] (this is usually the MainSequence).
Therefore if you ahave a sequencefile with two sequencecalls eg MainSequence and SubSequence. Then the expression called somewhere in MainSequence
'RunState.SequenceFile.Data.Seq[1].Locals.MyBoolean = True' will set the local boolean in SubSequence.


I have attached an example. In the MainSequence a step changes the value of Locals.MyResult in SubSequence from 10 to 16.

But once this has been changed it will always be set to 16. I haven't changed the ChangeCount so thats why the editor doesn't think the sequencefile has been changed.


Hope this helps

So this thread is ancient, but I still found it helpful.  It was also useful to know that you can use the Step.StepIndex parameter instead of hardcoding the index to the subsequence you're calling, like so:

RunState.SequenceFile.Data.Seq[Step.StepIndex].Requirements.Links[0]

I'm using this to customize the TestStand report to include the requirement property listed under that subsequence.

Correction, using Step.StepIndex as in my above post doesn't make any sense, it was only working by coincidence.  The following is what I wanted, using the name of the callee as the index:

RunState.SequenceFile.Data.Seq[Step.Module.SeqName].Requirements.Links[0]
