convert EA elements

[Tehila1]

Hello everybody!
I want to convert programmatically EA.Element which its type is Package, to EA.Package.
Any Idea?

Thanx

[Eve]

The easiest way would be to call Repository.GetPackageByGuid with the guid from the element.

[Geert Bellekens]

There should be no need for any conversion at all.
For each EA.Element with type 'Package' there exists a EA.Package equivalent.

Use the method suggested by Simon to get the corresponding object.

Hello!
Thanks for quick reply!
I'm still stuck with that issue:
I want to loop on all diagram element. This diagram is an owner of only packages. I want to refer the elements like packages:

foreach (EA.DiagramObject curElement in selectedDiagram.DiagramObjects)
                  {
                  int packageID=curElement.ElementID;
                  EA.Package package= Repository.GetPackageByID(packageID);
                  }

I accept this message :"Can't find matching ID"

Thanks in advance!

You have to read the response carefully

It says Repository.GetPackageBy[highlight]Guid[/highlight]

GetPackageBy[highlight]ID[/highlight]

OOPS- thank you for conversion of my attention!
but how do I access diagramObject's GUID?

[Geert Bellekens]

you first get the element using GetElementByID and then use the GUID of the element object.

Thanks a lot!
As you see I'm a new user of EA and this forum seems to be very helpful!

That won't work this way. From my Scripting book (chap 2.3)

If you issue

  package = Repository.GetPackageByID (package_element.PackageID);

then package will be Modeling Basics (which is likely not what you would expect) while

  package = Repository.GetPackageByID (package_element.MiscData(0));

will make package to be Line Styles. Note that the expected integer value might need a cast
from string in your programming language.

Your GetElementByID will get the package_element related to the package. So try:

Code: [Select]

foreach (EA.DiagramObject curElement in selectedDiagram.DiagramObjects)
                 {
                 int packageID=curElement.ElementID;
                 EA.Element element = Repository.GetElementByID(packageID);
                 EA.Package package= Repository.GetPackageByID(element.MiscData[0]);
                 }

(I have no idea how to address the first element of the array MiscData in the language you use.)

Q,

It should also work that way. You can verify yourself, the row in t_object has the same ea_guid as the row in t_package.

I just realized that a few days ago myself, because that is a lot easier then having to use the pdata1, casting to integer etc...
I'm not sure why we have been using that method for years now when there's a much easier alternative.

Ah! i was not aware of that. Thanks a bunch, Geert  

We've probably used that after I had asked Sparx how to do it. And that was their suggestion. Now, why are there two ways to do it? Who designed that? I will not ask

Thank you all for quick answers!

Hello!

I want to access programmatically classes which are owned by a diagram via a hyperlink for that diagram.
Is there an existing way to do so, or I must convert the diagram hyperlink to a regular diagram?

Thank you!

[qwerty]

The hyperlink is a special Text element. You will find it amongst the diagramObjects.

q.

[Tehila1]

Yes- The diagram hyperlink is a member of the diagram objects.
But, in order to access the 'Text' element we ought to convert it to EA.Diagram object.
Well- I did it like this:

foreach(EA.DiagramObject diagramObject in diagram.DiagramObjects)
                        {
EA.Element element= Repository.GetElementByID(diagramObject.ElementID);
}

Now. I would like to get the appropriate EA.Diagram
EA.Diagram diagram=Repository.GetDiagramByGuid(element.ElementGUID);
 but the diagram's GUID is different from the element's GUID. and an error was occurred: "Can't find matching ID"  

So how can I do it???
