How get actual class attributes from uml class [message #473297] Tue, 26 June 2007 05:01 Go to next message

Hi All,

With the uml2 API I could not find a way to get actual class attributes
(except class properties for relationship ends).
We can use umlClass.getAttributes() method to get attributes related to a
class. But it returns relationship ends also as attributes. The
getAttributes() method returns list of properties.
So tried with property.isAttribute(p) method to check those properties for
class attributes. But it always returns false. Also I could not understand
why this isAttribute() method requires a parameter. Because we are always
invoking this isAttribute() for property so what is the meaning of passing
another property type parameter to it.

Thanks and Regards,

Hi there,

You could use Property.getAssociation() != null, but this is, in my
opinion, not really an elegant solution. Ideally there should be some way
to get the list of attributes without inspecting each one of them. If
someone has a better idea, please post here. Thanks!

Regards,
Francis

Hi,

Thanks Francis,
But I think there must be a way to get those class attributes more easily
(as you mentioned in your mail).

Regards.

Hi uml user,

I think Francis is right, his suggestion seems to be the only way to figure
out what you want.
There does seem to be something wrong with Property#isAttribute(p) ... I'll
double check that one.

Lasith,

There is currently no convenient method for obtaining the attributes which
are not also association ends. Feel free to submit an enhancement request in
Bugzilla.

The isAttribute(Property) method requires an argument because the OCL query
from which it is generated was poorly defined in the UML specification:

[4] The query isAttribute() is true if the Property is defined as an
attribute of some classifier
context Property::isAttribute(p : Property) : Boolean
post: result = Classifier.allInstances->exists(c|
c.attribute->includes(p))

We'll open an issue with the OMG.

Hi Kenn,

Thanks for the reply.
But I can't understand the actual usage of isAttribute(Property) method.

Lasith,

I'm not sure the method has any practical use either, but it's in the
specification, so we need to include it in the API. One thing the method
will tell you is whether the property is owned by a classifier (as opposed
to a property that has no owner, or is perhaps a qualifier for another
property).
