5 years ago Depends is a syntactical relations analayzer. It does not focus on the runtime behavior. In above example, it will generate the following relations: 1, A inherit B 2, (some) create B (some) means the container which contains A* 1_PA1=new B 3, (some) use/set A 4, A calls Func
as explained above, based on the goal of depends, virtual method is no actual impact on the relation analysis.

5 years ago Thank you for the explanation. So the point 4. A will calls A::Func, not B::Func, right? Suppose Func is a virtual method of A and B override it.

5 years ago it is what I means, but I try to explain it more accurately: (Let's assume the instance of B is passed to function foo()) void foo(A* l_pA2){ l_pA2->Func(); } The result of depends is: function 'foo' calls A::Func(). No any relation with B generated. From design view, it means that foo only depends on A, it has no awareness of B, although in runtime, the actual called function is B::Func().

5 years ago Really appreciate the detail explanation. Thank you very much.
Is virtual method of C++ handled in latest version 0.9.0? case like below: class A:B virtual method Func() A l_pA1 = new B; A l_pA2 = l_pA1;
l_pA2->Func();
