'classIsInstantiated' substitution field

[Andreas_G]

Hello out there,

I try to generate code like the following

Code: [Select]

class MyClass : public MyTemplateClass<AnyType>
{
};

I know this is possible because I found in the code template 'Class Base' the substitution field [size=16]classIsInstantiated[/size]  

But I can't find how to set this value to [size=16]true[/size], and I also don't know how to set a value to [size=16]classArguments[/size] also in the 'Class Base'.

May be I have tomatos on my eyes, so please tell me, who to set this values in the GUI!

bye
Andreas

I think I found it.

It's in the Parameterized Classes (Templates)
Dialog.

Here you have to set the Tpye to Instantiated and enter some Arguments.

May be, I'm wrong, but is this not the wrong place for this parameters?  
Shouldn't it be in the Generalization Properties?

Explain me, if I'm wrong!

bye

Hello Andreas,

Sure, instantiation information could be on the generalization properties, but I don't see any reason why that is where it has to be.

Not that I'm saying there isn't any room for improvement.  There is and I know that there are plans to do that.

Hi Simon,

Sure, instantiation information could be on the generalization properties, but I don't see any reason why that is where it has to be.

I think one reason is multiple inheritance (I don't use it, but may be other users). If you need different parameters for each base class, it's not possilbe with the actual solution.

That's exactly right Andreas!

The Parameter Bindings should be on the Generalization Link not the Class!

The parameter list is defined on the Parameterized Class and the binding of the parameter value for a specific Generalization should be attached to the link.  Thus if you inherit from multiple sources, each one specifies what gets bound.

Yes, the current system doesn't handle templates with multiple inheritance.  We realize that, and as I said, we have plans to improve the template handling.
