LabView polymorphism?

[tadders]

Hi all,

I'm looking into using LabView object orientation but can't seem to find much about polymorphism.

I'm thinking of the C++ example where a parent class defines a method 'tune' and a child class overrides the method with its own 'tune' implementation.  A pointer to the parent class is then initialised with an instantiation of the child class.  Calling 'tune' on the pointer late binds and calls the child 'tune' implementation.

Can you do this in LabView 8.5?

Best regards

Phill

Hi,

Please find here some basic knowledge about Graphical Object-Oriented Programming. On this link you can find more information about Polymorphism in LabVIEW.

What you're looking for is called dynamic dispatch.

The links in the previous reply do not refer to LVOOP, so you should start by reading this and following the links it has, specifically the one detailing the design and the reasons behind it.

I also suggest you go to the LAVA forums and look through the OOP board. The LVOOP team manager posts there frequently and it has a lot of important discussion about how things work, why they work that way and if they should be changed.
