Re: [SysML Forum] Re: TriggerOnNestedPort Signature

[david reye]

Dan,

In the UML spec "from", "at", "after" and "when" are all keywords. Hence the use of guillemets in «from» is correct; it is not a typo (assuming they are keywords in the SysML spec ).

Interestingly, "via" is not listed as a keyword.

"when", "after" and "at" are all followed by an expression in parentheses (e.g. when(someCondition) ) so it probably makes sense to drop the guillemets around the keyword.

That's how I reason it anyway.

Cheers,

David

The SysML 1.3 spec specifies: "The nested port path is notated following a trigger signature with a string “‘«from» (’ <port-name> [‘,’ <port-name>]+‘)’” in the name string of the icon for the trigger."

Is there any rhyme or reason why it has ‘«from» (’...')' but InvocationOnNestedPortAction just has 'via', ChangeEvent uses 'when' and TimeEvent has 'after' and 'at'? Is this a typo and should be 'from ('...')'?

Thanks,

Dan
