Question

I want to specifically invoke the base class method; what’s the most concise way to do this? For example:

class Base
{
public:
  bool operator != (Base&);
};

class Child : public Base
{
public:
  bool operator != (Child& child_)
  {
    if(Base::operator!=(child_))  // Is there a more concise syntax than this?
      return true;

    // ... Some other comparisons that Base does not know about ...

    return false;
  }
};

Answer 1

No, that is as concise as it gets. Base::operator!= is the name of the method.

And yes, what you are doing is standard.

However, in your example (unless you have removed some code), you do not need Child::operator!= at all. It does the same thing as Base::operator!= will.
