As i have seen in several place where OCL expression is used to put some constraints. In gmfmap if we do the followings,|
Audit Container->Audit rule->Constraint,
we may include some OCL expression in Body part. I want to know how can i generate this OCL expression?
lets give a example: suppose i have nodeA and nodeB. I can draw only 1 line between them. not more than 1 or not 0.
or may be...there is a attribute of nodeA is rate. rate is a integer value and it should be between 50-100.
So to implement these constraints usually OCL is used(as i have seen).
but i cannot make my own OCL expression. what i have find in different tutorial is for those design only. How can i make OCL expression for my own design?
I hope i make you understand. If you have a question to answer my question, please ask me.
