I have a function argument of type class ,say Message(const ClassA& obj) .For animation,I believe I have to write animserialize function for type ClassA.

However I see that I dont have animserialize propoerty under a class , but only under Type.So should I create a new Type for the class and then define my serialize fns for it ? Can i not have these functions for a class as such.

You don't need to serialize a class passed as a parameter for animation.

What is the issue?

I jsut trying out some examples using animserialize functions.I read in the document,that I should write these functions when trying to animate comlex data types.

Please let me know in what scenarios I should be using these functions?
Any example would be of great help.

If you don't provide these functions then things will still work in animation but you'll just see addresses of the data rather than a textual representation. Exception to this is when you want to inject 'complex' data but you can deal with this by enhancing the capabilities in your actors and then nudge them through a simpler interface.

Having said that, in my opinion you should never have to do this. I know that may seem simplistic but 'complex types' don't get passed between objects in any system I've modeled. Classes do but they're defined by their behaviours (methods), not by their implementation.

I know that if you've come to Rhapsody from a software background that hasn't been completely OO then you may be sceptical. It takes time to evolve a mindset that makes it easy to model but Rhapsody gives good feedback. Basically, if it's complicated then it's probably not the best approach.
