Is this a good way to create an Instrument Registry using DVRs?

[Mark_L]

In the past I have used Single Element Queues (SEQ) and am now just learning how to use DVRs and the In-Place structure..

I am exploring developing a Registry List using DVRs.  Here is a scaled down block diagram which shows the essential parts of how it would work.  In other words, the stuff in the sequence structures would be in a subVI.  

1) Am I on the right track?

2) Is this pattern a good idea if Value is not a double but a very large array of doubles?

3) Are there any special gotchas to look out for?

For completeness, here is how it would be done with a queue.

Sure, that works as a way of getting references to instruments and such. You can go down that route, or install G# from VIPM and get reference based classes doing about the same thing. 😉

Yamaeda, thank you for the reply.  G# toolkit looks a little daunting for me at the moment.  I am hoping to find something a little more specific just concerning the Instrument Registry list and accessing data in the Instrument Objects in the list.  

Anyone else have a comment on my example?

I think I'd store the DVR itself in another class instead of passing around the DVR wire. I think G# does something similar, maybe?

You'd then be able to make child classes for specific instrument subgroups/types/etc and you'd get protection from someone accidentally using the DVR incorrectly.

OK.  Thank you.  I will code something up and get back with you all.
