title: How do I refer to an object of an object?
body: <p>A class circle creates and uses an class secant to calculate its diameter. Now a GUI class needs to get a field (number of iterations used by the numerical method called "secant" to make the calculation) from a particular secant object used by a particular circle object. How should I perform such a reference?</p>
  
  <p>Number of iterations is not a property of a circle. Should I force it to become that anyway?</p>
