Owned Elements [message #506159]

Hello All,

When I ask via getOwnedElements() all owned elements from a sequencediagram , it returns not all the elements .
If I do the same with other diagrams it went fine. Can anybody give a way in how I can get all the owned elements of a sequencediagram ?

I want to print these out as eg a String

Many thanks

Hi Randi,

what do you mean by sequencediagram? Do you mean UML::Interaction
element? If so, please have a look at the semantics of the derived union
ownedElements. It will only return the directly owned elements of an
element, since the additional operation allOwnedElements() will return
all directly and indirectly ownedElements of UML::Interaction e.g.

Thank you Marc , this solved the problem. Maybe an other question related to this. When I have a component eg
LifelineImpl@13d28e3 (name: :object1, visibility: <unset>)
I want to be sure I get all the attributes of this LifeLine , but I only get a name and visibility.Are this the only 2 attributes of a LifeLine.So how can I get all the attributes within Eclipse o a component/elemnt from a Interactiondiagram?

Many thanks

Again, take a look in the UML2 spec, to gather the relevant information,
but:

A Lifeline is a NamedElement, hence it owns mainly these both
attributes. However, a lifeline takes part in many association
relationsships. Since lifeline doesn't provide a union like
Classifier::/feature, which list you all features of this element, you
have to collect them manually, by investigating the spec...

Hello ,

MAny thanks for the answer. Is it so that in Eclipse all attributes I can find in de UMLSpec also are implemented in Eclipse ? Or have they made an abstratction , and only implemented the most important ? And if they have implented only the most important , where can I find those items which they have not implemented ?

Thanks
