Can I use 'self' in sequence diagram? [message #1022117]

Hi,

Can I use the keyword 'self' as lifeline-ident and connect it to an
arbitrary class in Papyrus 0.9.2?

TIA

Yes you can

see http://www.eclipse.org/forums/index.php/t/447570/

According to the UML spec

If the name is the keyword self, then the Lifeline represents the object of the classifier that encloses the Interaction that owns the Lifeline. Ports of the encloser may be shown separately even when self is included.

Also See the notation rules for lifelines in UML 2.5 beta 1:

<lifelineident> ::= ([<connectable-element-name>['[' <selector> ']']]
[: <class_name>] [decomposition]) | 'self'
<selector> ::= <expression>
<decomposition> ::= 'ref' <interactionident> ['strict']

OK, thanks. Sadly I do not quit understand it. You mentioned "I created
two Role Bindings in CollaborationUse with dependencies." in one of your
responses. How did you do that? By going to the model and choosing "new
child->new CollaborationUse" with the righ mouse button on the
appropriate class or by drawing some diagram?

TIA
