In Visual Studio 2003/2005 (C++) - I can create a class. I hide both the Copy Constructor and operator=(Obj& obj) method by declaring them in the private section - and not implementing them.

For example:

namespace a {

namespace b {

namespace c {

class OldName
{

public:

OldName() { }

private:

OldName(const OldName&);

OldName& operator=(const OldName&);

};

}

}

}




Now, refactor the name of the class by hovering over the "class OldName" section, clicking the arrow and changing the class name.

You will find all the type names change EXCEPT the arguments in the in hidden constructor and operator methods. They remain OldName. Mind you, the name of the copy constructor and return value of the operator=(const OldName&) do indeed change.

Hope that helps,

-Luther


namespace a {

namespace b {

namespace c {

class NewName
{

public:

NewName() { }

private:

NewName(const OldName&);

NewName& operator=(const OldName&);

};

}

}

}

For creating noncopyable classes I'd suggest inheriting from boost::noncopyable from the Boost.Utility library

This is a known bug. VA is confused since there is no parameter name. I know you don't need a parameter name for this to compile, but until this bug is fixed you need to add a parameter name for rename to work correctly. So change the code to read:

        OldName(const OldName&rhs);
        OldName& operator=(const OldName&rhs);


case=3027
