Hello,

How do I know what are the classes from certain package? Is there an operation for such thing?

I will include an example, let's say I have this model:

Package A:
- Class: aa
- Class: bb
- Class: cc
Package B:
- Class: aa
- Class: ee

And I wanna create two folders, like this:

A/aa
A/bb
A/cc
B/aa
B/ee

But as far as I tried what I get looks like this (which I don't want, obviously):

A/aa
A/bb
A/cc
A/ee
B/aa
B/bb
B/cc
B/ee

If anyone could help me.
Thanks in advance.

Hi Patricia,

I suspect that your code looks something like this:

for (p in Package.all) {
for (c in Class.all) {
// Create directory
}
}

while it should look like this instead:

for (p in Package.all) {
for (c in p.classes) { // Iterate only through the classes of that package
// Create directory
}
}

If this is not the case, please feel free to attach a minimal example [1] and I'll have a closer look at this.

Cheers,
Dimitris

Hi Dimitris,

Yes, I have something like that but I don't know how to do the p.classes line, as it gives me this error:

Property 'classes' not found in object org.eclipse.uml2.uml.internal.impl.PackageImpl@97fb72 [name: Recursive, visibility: <unset>] [URI: null]

Minimal attached.

Hi Patricia,

Would the following do the trick?

for (c in p.packagedElement.select(e|e.isTypeOf(Class))) { ... }

The EPackage Registry view may help with similar problems in the future:

I just tried that line but it gives me this error:

Method 'isTypeOf' not found for: org.eclipse.uml2.uml.internal.impl.ClassImpl@1651826 [name: Graph, visibility: <unset>] [isLeaf: false, isAbstract: false, isFinalSpecialization: false] [isActive: false]
