Question & Answer
Question
How do you use IBM Rational Rhapsody Java API to retrieve the model element which is set in a tag element?
Cause
You can call IRPTag.getValue() to obtain element name set in a tag or call IRPTag.getDeclaration() to further retrieve the element metaclass info; however, this is still not sufficient for you to easily retrieve the element itself which is set in a model tag.
Answer
You should call IRPTag.getValueSpecifications() and parse the returned collection into IRPInstanceValue data type. Sample code is shown as below.

Iterator looper;
app = RhapsodyAppServer.getActiveRhapsodyApplication();
prj = app.activeProject();
sel = (IRPModelElement)app.getSelectedElement();
//if the selected element is an instance of Tag
if (sel instanceof IRPTag){
tag = (IRPTag)sel;
//call getValueSpecifications() to retrieve tag value collection
valSpecs = tag.getValueSpecifications();
looper = valSpecs.toList().iterator();
//call getValue() to retrieve each element instance set as the tag value
while (looper.hasNext()){
ins = (IRPInstanceValue)looper.next();
elem = ins.getValue();
}
}
