Generation of Associations as a Property

[dirc]

When I define an Association and define a target Role, I can set it to private or public.

What I really want to be able to do is to set it to private and automatically generate a Property for this field.

Further to this, it would be able to be able to optionally set the property to only have a Setter. The reason for this is that I am creating a 0.* association and I want the collection class to be a read only property.

Can anyone give me some pointers as to how to best acheive this?

Many thanks

You can create getters/setters from within the attribute creation. Once you have attributes you can select them from the drop down in associations. It is not possible to create an attribute from a value entered in an association.

I know this is not standard behaviour.. I was thinking something along the lines of changing the way the code for an association is generated.

I will put this forward as a feature request.. until then has anyone any clever schemes to get this done?

Try using the transformation templates.

The default C# and Java templates do part of what you want, but I'm guessing you want to do a bit more.

Start with that, if it's C# add a readonly tag to the property created if using a collection class (in the Linked Attribute template) and you could even automatically generate add/remove remove methods.

OK... done it.. does anyone want the template?
