Provide a malleable "Traverse For G Objects" function

[TurboPhil]

We've all probably found ourselves writing various forms of this:

It would be great if there was a malleable version of the "Traverse For G Objects" function that shipped with LabVIEW to save a few headaches. Rather than passing in a string for the class name, and then adding a downstream ToMoreSpecific operation, it could accept the refnum constant (in the above example, the "Control" class ref) and return an array already cast to that class.

Could not give this a kudos fast enough!

I tried making a malleable of this myself, but ran into issues:

It turns out, you can't get the ClassName from a refnum constant (the constant is not a *valid* reference). You *could* still require passing in the class name along with the class itself, but that feels lame.

You can use Get Refnum Information.vi on the reference control.

Get Refnum Information.vi returns an "VI Server generic type" enum. There seems to be a 1-1 mapping between classname and the enum value.

One could probably script something to change a class constant to all possible classes, run Get Refnum Information.vi on each value, to get the enum value...

Here you have it !
