Choose the correct answer:

Can State Machine Events have Features?

AYes. they can

BYes. they can. but only when the modeled Events also extend Classifier.

CNo. they can not. because State Machine Events are not Classifiers.

DNo. they can not. because UML State Machines do not have an Event concept.

Show Suggested Answer

Suggested Answer: C

State Machine Events in UML are triggers for transitions and do not classify as objects or classifiers; thus they do not inherently have features:

A . Incorrect, because State Machine Events are not treated as classifiers with features.

B . Incorrect, though it hints at an extended use case, State Machine Events do not extend classifiers in standard UML usage.

C . Correct, State Machine Events are not Classifiers and therefore cannot have features such as properties or operations.

D . Incorrect, because UML State Machines certainly have an Event concept, but these Events are not classified as having features.

UML Specification: State Machine chapter, specifically sections discussing the nature of events and triggers.

Further insights can be found in the event and trigger management sections of the UML 2.5 Documentation.

Wait, are we sure about this? I thought State Machines couldn't have features at all!

C is definitely wrong, State Machine Events are part of UML.

I practiced a similar question, and I think the answer is B. It makes sense that they can have features if they extend Classifier.

I’m a bit confused about the Event concept in UML State Machines. I thought they did have it, but maybe I misread something.

I remember studying that State Machine Events are not Classifiers, so I feel like option C might be correct.

I think State Machine Events can have features, but I'm not sure if it's only when they extend Classifier. That sounds familiar.

I'm a bit confused by this question. My understanding is that State Machine Events are not Classifiers, so they shouldn't be able to have Features. But I'll double-check the details before answering.

Okay, I think I know the answer to this. State Machine Events can have Features, but only if the Events also extend Classifier. I'm confident that's the correct answer.

Hmm, this is a tricky one. I'm not sure if State Machine Events can have Features or not. I'll have to review the UML specification to be sure.

I'm pretty sure State Machine Events can have Features, but I'm not 100% certain. I'll need to think this through carefully.

Wait, State Machine Events can have Features? I thought they were just for triggering transitions. This UML stuff is getting too complicated for me.

Option D, really? UML State Machines definitely have an Event concept. This question is way too easy.

I'm going to have to go with option C. State Machine Events are not Classifiers, so they can't have Features. This seems like a pretty straightforward question.

Hmm, I think option B is the correct answer. State Machine Events can have Features, but only if they extend Classifier. The UML standard is pretty clear on this.
