Adding option to specify protocols to import when using transformable type

[rtircher]

Allows to specify a attributeValueClassName similar to id<MyProtocol>
Mogenerator can now insert @protocol MyProtocol; in the machine header files. Another user info needs to be added where the key is attributeTransformableProtocols and the value is a comma separated list of the protocols used for the type. For the above example, it would just be MyProtocol as value.

Looks good. Could you please extend the Test Dir to exercise your enhancement?

I'm thinking adding a transformable attribute with a custom protocol (myTransformableWithProtocol?) to ParentMO.

After extending the model, rake to ensure that codegen is correct, it compiles and runs.

Finally got to add the tests for this.

Looks like I snuck in a fix the modified Test Dir's data model out from underneath you and now is unmergable.

Could you update your fork and reapply your model file change? That should do it. I think. You may have to temporarily replace your model file with my current model file just to get the merge to work and then reapply your model change.

[rtircher]

Here you go this should do it.

[rentzsch]

That does it, thanks!

I am using transformable attributes. But I don't quite understand this syntax. Would you mind adding an example to this feature?
