Suggestions and Requests / Re: Perforce support

« on: December 07, 2004, 07:47:52 am »

Hi,

I haven't tried it but Perforce does come with an excellent SCC adaptor, allowing for integration in VisualStudio and so on.

Have you tried using it for EA?

Let us know!

Suggestions and Requests / Re: Custom emf for "lollipop" notation?

« on: April 14, 2004, 11:43:39 pm »

Hi Manfred,

you suggest: "extending the Interface metaclass through stereotypes".

This is exactly what I have in mind!

But: for stereotyped refinements of an Interface (and hence the refinement of semantics of the meta level M2 class) you still have no way to associate a different visual representation (lollipop like).

And hey: thanks for the hint that UML is not just pictures...

Suggestions and Requests / Custom emf for "lollipop" notation?

« on: April 14, 2004, 05:20:30 am »

Hi,

we are modeling certain types of interfaces that need graphical representation different from the lollipop/socket.
While you can give alternative EMF's for a stereotype when displayed in "box" notation, it would be great to also allow changing the display of the lollipops, according to stereotype.

What do you think?

Suggestions and Requests / EAP file name in XMI export

« on: April 14, 2004, 05:28:50 am »

Hi,

our tool chain evaluates the XMI export of a model.

Would it be possible that a new tagged value containing the EAP file name (if based on a file) is added?

The implementation of such a feature should be straightforward...

Thanks for a quick note.

General Board / Re: XMI import problem -- Invalid unicode

« on: April 10, 2005, 11:36:36 pm »

Have you tried reading the XMI file with another XML parser? I am not sure it is the "l" (lower letter "L") that is confusing the parser:

In UTF-8 characters (so-called codepoints) are encoded in byte sequences with a length between 1 and 6 bytes. All ASCII characters (<128) are encoded with the same single byte value in UTF-8 (UTF-8 is ASCII compatible). The byte sequences are *not* subject to byte order of the used platform.

Using a tool like dos2unix might do s/th bad. Is the tool Unicode enabled or does it simply assume ASCII files and just switched the codes for CR/LF?

Could you maybe export a file in ASCII or latin-1 instead?

Just some thoughts,
Mike

Hi there,

in a different context I also had a lot of trouble with the MySQL OBDC driver.

I then switched from MySQL to PostgreSQL and this works like a charme. (PG is also much more capable and SQL compliant than MySQL!).

Haven't tried EA with PgSQL, but maybe this gives you another option to look at.

General Board / Re: On generating DDL...

« on: August 26, 2005, 07:26:10 am »

Hey Hansje,

not sure I got your question the right way, but if you mean "table" when you say "object", you certainly can create the DDL for a whole bunch of tables, simply by selecting to generate the DDL for a whole package.

EA then even asks you whether you want to have a DDL file per table or a single DDL file for all classes/tables generated.

Just right click on a package in the tree browser and select "Code Engineering/Generate DDL..."

General Board / Re: generate XML from model

« on: July 19, 2005, 07:28:59 am »

Hi Bernd,

in general there are a few ways to create any kind of text output including XML from a model, e.g.

o Export the model's XMI and have an XSLT transform it into your own XML structure

o Write EA Code Templates to directly generate your XML code. However, I think only class diagrams are currently supported to be used for generation.

o Either parse the XMI into your own datastructures or directly use EA's COM API to query the model, then generate your XML with your own generator.

Just a few thoughts,
Mike

General Board / Ordering run state

« on: April 27, 2005, 03:38:41 am »

Dear all,

do you know of a way to sort the runstates of an object after they have been entered?

It seems EA simply keeps the order of insertion. I could not find a way (except possibly hacking XMI) to modifiy this afterwards.

This is kind of awkward...  :-/

Thanks,
Mike

General Board / Modeling question: "Composite" link?

« on: April 21, 2005, 07:13:34 am »

Dear all,

in a class diagram I might have defined a composite aggregation between class "A" (parent) and class "B" (child).

In a corresponding object diagram I show instances "a:A" and "b:B".

Now, UML says that between instance specifications in an object diagram you typically have links that may carry role names and even navigation arrows:

An instance specification whose classifier is an association represents a link and is shown using the same notation as for an association, but the solid path or paths connect instance specifications rather than classifiers. It is not necessary to show an underlined name where it is clear from its connection to instance specifications that it represents a link and not an association. End names can adorn the ends. Navigation arrows can be shown, but if shown, they must agree with the navigation of the association ends. (from UML Superstructure/03-08-02)

Would it also be fine to also show the filled diamond to indicate composite aggregation? IMHO, this would clarify the diagram and the semantics is the same as for navigation arrows ("must be consistent with class diagram")...

Any opinions?

Thanks,
Mike

Hi,

it is currently not possible, but there seems to be a possible workaround... See this previous post:

General Board / Re: Graphical Dependencies

Hi there,

dependencies like that are not created automatically. If you want to explicitly show it, that you'h have to draw it manually.

General Board / Re: GUI Generation

« on: February 24, 2005, 11:06:48 pm »

Hi Ta,

not sure I understand the question completely, but AFAIK there is no way to generate code from UI sterotypes w/o adding quite some stuff.

In addition to the programming language you would need to specify the UI framework to be used.

Theoretically you could try to define a new "language" let's say "MFC" (just an name for a framework, ... :-) and set up the appropriate code templates.

However, I am not sure how far EA generator capabilities will get you there...

Also you would need to introduce certain design rules, like: instead of just moving a control class in front of a window class, giving you the visual impression of containment, you then need to actually create the containment relation in the model...

I doubt this would be paying off in the end.

General Board / Re: Anyone using CVS?

« on: February 07, 2005, 12:13:27 am »

Hi there,

we were trying out the CVS support recently (build 744) and it worked as expected.

Can you quickly describe the steps you're doing and when exactly it starts hanging?

What kind of cvs access are you using (pserver, file, ...)?
