How to specify Delphi interface GUID in Enterprise Architect?

Question

I'm using Enterprise Architect code generation feature to export my models to Delphi code. Is there a way to specify interface GUIDs in EA so that interfaces are completely defined in the output code?

Example:

ILogger = interface
  procedure Log(AMessage: ILoggerMessage);
end;

should be

ILogger = interface
['{16B77CF4-4219-412D-B1F3-20E29E2E9D9E}']
  procedure Log(AMessage: ILoggerMessage);
end;

CTRL + SHIFT + G

No. Delphi has no idea whether you'll need a GUID or not, as not all interfaces have to have one. (Interfaces that aren't intended for COM and don't implement IDispatch, for instance.) The IDE can't read your mind (yet - maybe there's hope for the future ), and can't know what type of interface you're planning on creating.

Seems that EA does not support interfaces as in COM programming. But, you can try use the template editing feature to change the way code is generated...

Answer 4

You should add to ILogger TaggedValue Attribute with value containing GUID in form that Delphi likes:

Attribute=['{16B77CF4-4219-412D-B1F3-20E29E2E9D9E}']

then you should modify Code Generation Template Class Body and add

%classTag:"Attribute"%

as the second line (should be after %if elemType == "Interface"%) Now EA should properly generate code with GUID's. EA imports it well but fails to generate properly.

This is a quick fix for interfaces only, it's been long time since I programmed in Delphi so I'm not sure if classes can have such attributes as well, therefore solution is limited to interfaces, for now :).
