Dominance (C++)

In the C++ programming language, dominance implies a specific behaviour of symbol disambiguation in virtual inheritance. Consider the following example:

<source lang="cpp"> class Parent { public:

   void function();

};

class Child1 : public virtual Parent { public:

   void function();

};

class Child2 : public virtual Parent { };

class Grandchild : public Child1, public Child2 { public:

  Grandchild()
   {
       function();
   }

}; </source>

In the Grandchild call to function(), Child1::function is implied, because Child1 is derived from Parent and thus Child1::function "dominates" Parent::function.
