there is a simple question that confusing me
I would like to describe an operation which is similar to as follows:
inv: man.age > 18
inv: man.isAdult() = true
while Person and Motor are two different classes
And there is an association end man whose tyep is Person
However, when I try the expression "man.isAdult() = true", it results in error
while the expression "man.age>18" is OK.
Did I write a wrong OCL expression if I want to describe an expression that refers to a function call between two classes?
If so, how can I fix it?
thanks a lot.
