Object Class Hierarchy

[hugo_fr]

Hi all,

I wish for this VI :

The ClassName property is easy, but how retrieving the class inheritance hierarchy ?

Any idea ?

Can you post what you've already done so we can use it as a starting point?

One thing you can try to do to automate this is

1. Open the LV help.
2. Go to the property and method reference.
3. Right click it and choose to print all of it.
4. This will open a window with all the properties and methods as a long HTML page.
5. You can right click this window to get the source of the HTML, which you can now save or you can print it to PDF or to Office.
6. Now you can parse it. For each class, you get the inheritance list at the start.
7. You can use this info to build a static tree, which you can then use to extract the data.

Not particularly elegant, but it should probably work.

I have a VI that will give you a generic's hierarchy.

I can upload it after work.

I did this VI more as an experiment in vi scripting than to be "good."

I would recommend creating a static hierarchy and simply returning the section of interest as yair suggested above if you need this to be blisteringly fast.

Hi Jon,

unfortunately your code does not work:

It works if the input is not a constant but a true ref.

The basic problem with both methods is that they're inherently manual. Mine has some advantage in that once you have the parsing code, adding a bunch of new classes is probably easier, but it's limited to what appears in the help.

Jon's method is limited to the classes placed there by the user, but isn't limited to what NI placed in the help. I don't know of any way of getting all the class references automatically, but maybe someone else does.

Thanks for help.

I did this code, quickly, manually, but work at this time and can evolve later.

The topic Saving all properties for Gobject contains a similar solution in the NI PropSaver library : PropSaver.llb\PropSaver - Predefined Property List.vi
