Behavior : State Machine Diagrams - Transitions - Events
5 important questions on Behavior : State Machine Diagrams - Transitions - Events
Where do we place the annotation of a event?
If more than one event may trigger the transitions, how do we write the events?
An event in a State Machine Diagram is essentially the same as an event in an Activity Diagram.
It can be..
- A signal arriving or an operation being called : that is a message arriving in Sequence Diagram.
- It can also be a timer expiring
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
If the state machine is for a classifier, you should find any arriving signal in the ..........
Similarly, an operation being called would be in the operations compartment (or in an inherited operations compartment).
A special reserved trigger, “all,” matches any received event, whether operation or signal, that the object is prepared for.
When the arriving event conveys ....... , specific values may be shown in the ....... list as done in Sequence Diagrams
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
