I want to call update for each derived object without a loop, this is the code that produces the loop from method “update()”. How to solve it the right way?

#include <iostream>

class Base {
public:
  virtual void update(Base *b1) {
    this->updateInternal();
  }

  virtual void updateInternal() = 0;
};

class DerivedClass1 : public virtual Base 
{
public:
  void updateInternal() override {
    std::cout << "DerivedClass1::updateInternal()" << std::endl;
  }
};

class DerivedClass2 : public virtual Base 
{
public:
  void updateInternal() override {
    std::cout << "DerivedClass2::updateInternal()" << std::endl;
  }
};

class DerivedClassSuper : public virtual DerivedClass1, public virtual DerivedClass2
{
  void updateInternal() override {
    std::cout << "DerivedClassSuper::updateInternal()" << std::endl; // <-- This is the first to be called, LOOP
    std::cout << "DerivedClass1::update(this)" << std::endl; // <-- This is the second to be called
    DerivedClass1::update(this); // <-- This is the third to be called, LOOP
    std::cout << "DerivedClass2::update(this)" << std::endl; // <-- This is the fourth to be called, but never reached
    DerivedClass2::update(this);
  }
};

int main() {
  DerivedClassSuper d;
  d.update(&d); // <-- Start the chain of updates
  /*
    DerivedClassSuper::updateInternal()
    DerivedClass1::update(this)
    DerivedClassSuper::updateInternal()
    DerivedClass1::update(this)
    DerivedClassSuper::updateInternal()
    DerivedClass1::update(this)
    DerivedClassSuper::updateInternal()
    DerivedClass1::update(this)
    DerivedClassSuper::updateInternal()
    DerivedClass1::update(this)
  */
  return 0;
}

The problem is that this will produce a loop in update() because updateInternal() is called.
This is the output of the loop after calling update:

DerivedClassSuper::updateInternal()

DerivedClass1::update(this)

DerivedClassSuper::updateInternal()

DerivedClass1::update(this)

DerivedClassSuper::updateInternal()

DerivedClass1::update(this)

DerivedClassSuper::updateInternal()

DerivedClass1::update(this)

DerivedClassSuper::updateInternal()

DerivedClass1::update(this)

What is the best and nicest solution for this problem?

Thank you!
