[Quantlib-dev] Looping dependencies

[Luca B. <luc...@gm...>]

I noticed that the current implementation of LazyObjects generates
infinite recursions
in the case the dependency hierarchy among Observer/Observable objects
contains loops.

A suggestion to break the infinite recursion is to replace the update()
method as follows:

 void LazyObject::update() {

      if (!frozen_&& calculated_){
        //
        // Set calculated_=false before calling notifyObservers()
        //
        calculated_ = false;

        notifyObservers();
      }

      calculated_ = false;
 }
