Hello,

this model: https://wiki.eclipse.org/Papyrus/UserGuide/ModelExecution contained two nested classifiers:

- IncrementClassifierBehavior
- incrementMethod

how do you add nested classifiers to a class (given that there aren't any nested Classifier Objects in the Object Palette)?

What exactly is a nested classifier? Why do you need it to animate a class?

Many thanks.

Philippe

Hi Philippe,

A nestedClassifier is just any Classifier owned by a Class. So creating e.g. a Class B as a child of Class A makes B a nestedClassifier.
You can easily do that from the Model Explorer: select Class A, right-click it and click New Child | Class.

Animation of a Class is of course not mandatory. If you want to specify for some reason the behavior of a Class, you could do so.
Can e.g. be useful if your Class represents an active Thread in an application. In that case you could be interested in specifying the background behavior that is continuously executed by the thread (as opposed to the behavior activated by calling a specific method).
