Best way to access a class for read/write from multiple other classes?

[ijustlovemath]

I need runtime to be preserved on a class that gets read to and written to by other classes. They share no common ancestry. The read/writes will be synchronous so there's no race conditions to worry about. My idea is to just have the class be private data of all the classes that need to access it and do a "handoff" between classes, eg bundling and unbundling it into the classes that need it. This seems messy though. Any ideas?

One idea is to use a functional global, but I don't think Labview classes would like that.

AE's can work but can also put a restriction on how re-usable your code will be.

I think you are looking for a Singleton Design pattern.

Search this site, there used tobe links and examples.

I use a Data Value Reference in this situation.  You just make a DVR that contains your shared class and then pass that DVR into all of your other objects at their initialization.  Since everybody who needs to alter the data has a reference to the data, everybody can change it inside of their private methods via an In Place Element Structure.

You can install G# and use referrence based classes, which'd make it simple enough. 🙂

They basically work like Crossrulz suggest.

Is G# supported in the runtime engine?

Yes.
