NOTE: This is a semi-followup to a discussion on the mda-discussion group. A spliced state model is one that exists, for example, partly in a superclass and...
... I usually don't bother with a parent class, but instead rely on flexible tools to allow me to create "superstates" within a class diagram. This is possible...
Responding to Marco... ... The models clearly need to be CMed because they represent to original sources. If there were any changes to the transformation...
Responding to Riemenschneider... ... My recollection of that discussion was that Sally Shlaer stepped in just before it got to the point of death threats and...
... just ... I would actually term this as: " "splicing" referred only to the interpretive work the translation engine had to do to construct the individual...
... This isn't really the same as a spliced state model, because a spliced state model is executing generic behavior in the superclass state model, not...
Responding to Riemenschneider... ... OK. ... Right. That view led to the debate to begin with -- the notion that somehow a superclass state machine had its...

Responding to Riemenschneider... ... Note "...in the first example". In your first example you had a single instance already in hand and navigated down the...
... Ah! The semantics of OO! ;-) Maybe we need to clarify whether we are talking about set instances, OOA instances, or OOPL instances, or what the rules are...
Responding to Riemenschneider... ... As you point out, there is a rational for defining the sets. But the syntax "create object instance" of c2 seems highly...
The concept of "assigner" is defined [pg 219] as "a state machine that serves as a single point of control for creating links on competitive associations"....
Responding to Ring... ... No. I believe it is best to think of critters like the Assigner as examples of a GoF Singleton design pattern where it is important...
... Well, this could be said to be confusing, but a superclass and subclass are distinct OOA elements. "create object instance" just denotes creating an...
Responding to Riemenschneider... ... Class2 is an OOA model element that is _part of_ an OOA subclassing definition. When that definition is implemented there...

Hi. Where can I find more info (docs, tutorials, etc.) about UML 2 diagrams, specially Activity Diagram and Composite Structure Diagram? Thanks....

I was (re)reading the section on Use Cases in the Executable UML book today and got to section 4.4.1 when it occured to me that a Use Case diagram isn't all...
