Find a class with a given Stereotype. [message #50850]

Hello,

I try to understand a little bit how the emft query/statement works (doesn't
really want to use OCL). Up to now, I have created some basic queries (find a
class having a specific attribute). But now, I would like to retrieve all the
elements stereotyped by a given stereotype.

I know that a stereotype is applied on a specific element with an association
base_/extension_. But I don't know how to create this condition. I have
investigated on using #isApplied(Stereotype), but without success.

Best Regards

Hello François,

Couldn't you use a condition something like this in your query?

public class StereotypeAppliedCondition extends EObjectCondition {
private Stereotype s;

public StereotypeAppliedCondition(Stereotype s) {
this.s = s;
}

public boolean isSatisfied(EObject eObj) {
if (eObj instanceof Element) {
return (((Element)eObj).isStereotypeApplied(s));
}
// Not a UML2 object, therefore, no stereotype is applied
return false;
}
}

I hope this helps,
Chris

Hello,

Thanks a lot. I have finally realized my query by providing a specific
BooleanAdapter, but your solution sounds better.

I have to confess that I have some difficulties to write queries on EFeatures...

Hopping to become good enough to help others people.

We are just building something like a Catalog of OCL expressions for UML2.
We dont have it yet online but I will post an adress if we have one.
The solution for your question:

self.getAppliedStereotypes()->exists(s : Stereotype |s.qualifiedName =
'test::test')

to get the qualified name, select the stereotype and say self.qualifiedName
