I wish to model an asynchornous message sent from an actor into my system on a SysML Sequence Diagram.
I have created a signal element in my model and have created a message from my actor to my system. I have set the "Control Flow Type Sync" to "Asynchoronous" and the Kind to "Signal" on the message properties dialogue. I have then selected the appropriate «signal» that I want this message to represent by pressing the "signal" button on the same dialogue screen and locating it within the browser.
Now I want to specify a reception on the target block...
I read in the EA help that:
"To define a reception, create an operation in the receiving object and assign the stereotype <<signal>> to it. The reception has the same name as the signal that the object can receive."see
http://www.sparxsystems.com/enterprise_architect_user_guide/8.0/modeling_languages/signal_element.htmlWhen I did this, I noticed that the list of
predefined stereotypes available for an operation did not include «signal» (or "reception" or anything else that looked relevant). I therefore concluded that I simply had to type the name of the stereotype into the box rather than browse for it...
I have done this as described and the block representing my system now has a stereotyped operation with the same name as my signal...
Now my question:
What links (if any) exist between this (supposed) reception and the signal itself?
Background:
I want there to be traceability between the signal events I create in my model and the receptions themselves. It is of little use to me to have an operation with a name that matches the signal - what happens if in time the signal name were to change? Would I have to go through and manually change all receptions?
I plan to use these sequence diagrams to create «Interface Blocks» to type «Proxy Ports»
Note: when I am creating my sequence diagrams I drag the target block onto the diagram as a "link" not a "lifeline". I don't know what advantages/disadvantages that might cause (other than preventing my model from rapidly filling up with multiple instances of my blocks!)
