How to get "tagged values" from an attribute of class in UML2.0 [message #1063642]

Hello

I have an UML class with attributes. I would like to know how I can get all Taggues values of each attribute.

Thank you for your help.

Use one of the #getAppliedStereotypes() variations in the Element metaclass (everything in UML is an element).

When i use class.getAppliedStereotypes().getKeyword() it return nothing but my class is stereotype <<singleton>>. I know that and it is possible the method class.getkeyword() is working. Everything I get using getAppliedStereotypes().
Is empty and I don't know how to proceed.
Nevertheless, I think that a taggues value is a stereotype in UML2, isn't it?
Thank you for your advice.

A stereotype application connects a stereotype to an element (and instance of the stereotype) and describes the values of the stereotype attributes in that instance. Tagged values are no longer supported in UML, and were replaced by stereotype attributes.

You query the values of the stereotype attributes in a particular stereotype application using Element#getValue(Stereotype, String attributeName). You determine whih stereotypes apply to an element using Element#getAppliedStereotypes(). You find out what attributes are available on the Stereotype using Stereotype#getOwnedAttributes(). You can also use UMLUtil.getTaggedValue(String stereotypeName, String attributeName) to get one particular value. There is a wealth of stereotype-related API in Element, Stereotype and UMLUtil, get familiar with them.

If #getAppliedStereotypes() returns an empty list and you are positive there are stereotypes applied to the element in question, you may be suffering of an unresolved profile reference in the model. Does yourPackage.getAppliedProfiles() return an empty list as well? Can you paste your model here?

Hello,

Thank you for your advice.

I cannot paste my model here because I'm working on a confidential project. However, myPackage.getAppliedProfiles() return and emty list but getKeyword() return a specific stereotyped when it exists.

Keywords and stereotypes are unrelated features.

Try to reproduce the problem using a simpler model then, and post that one here. Or omit the guts of the model file and provide only the top elements. For instance, the root xmi:XMI element and all the profileApplication elements, like this:

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="20110701" xmlns:xmi="http://www.omg.org/spec/XMI/20110701" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" xmlns:kirra="models/kirra" xmlns:mdd_extensions="profiles/mdd_extensions" xmlns:uml="http://www.eclipse.org/uml2/4.0.0/UML" xsi:schemaLocation="models/kirra platform:/plugin/com.abstratt.kirra.mdd.core/models/kirra.uml#_http2F2Fwww.eclipse.org2Fuml22F2.0.02FUML-kirra profiles/mdd_extensions pathmap://MDD_PROFILES/mdd_extensions.uml#_http2F2Fwww.eclipse.org2Fuml22F2.0.02FUML-mdd_extensions">

</xmi:XMI>

I suspect getAppliedProfiles() is returning an empty list because of a model reference (URI) not being resolved, the #1 issue people struggle with in this forum.
