Polymorphic functions are not recognized by indexer [message #876865] Fri, 25 May 2012 08:11 Go to next message

I have a base pointer initialized with a derived class

Base* ptr = new Derived();
ptr->foo(); (foo is a virtual function. Exists in both classes)


Surprisingly eclispe code navigation doesn't open the Derived class foo() function but rather the foo() from Base class.

Any suggestion how to make indexer to work for this ?

In order to make the above more clear...Trying to do some code navigation and I select the ptr->foo() function while pressing F3 instead of going to foo() of the derived class I am going to the foo() of the basic class.

I imagine for sure somebody has encountered such an issue since this is just basic polymorphism. Any idea how to have the correct display for this ?

Hi,

I checked java behavior and it behaves as CDT. You are expecting from CDT indexer too much Smile

How would you expect it to behave in use case below?

Base* ptr = new Base();

if (condition)
{
ptr = new Derived();
}

ptr->foo();


Thanks,
Yevgeny

All source navigators gives you the option to select which one you want to call. They don't really take you to Derived class foo() function but a prompt box is opening and they are asking you ...Derived:foo or Base:foo ?

Since this is quite basic (at least I have seen it in many IDEs) I am wondering whether this is a configuration issue in eclipse for C++

This navigation to virtual function is a lot better in CDT than in Visual Studio/Visual Assist. Just press Ctrl+T to watch the hierarchy of types that overload this virtual function.
