 *  This method can be overloaded through the hierarchy enabling a

 *  the returned argument can be of the more derived type.
 *
 *  Example:
 *  \code
 *  class xyzView : public dtkAbstractView
 *  {
 *    ...
 *    xyzView *clone(void); // Covariant returned argument
 *    ...

//! Enables to make a deep copy of the attributes through the class
//! hierarchy.
/*!
 *  This method is called by the assignement operator which delegates
 *  the copy process. When re-implementing this method into a derived
 *  class of dtkAbstractView, one must called first the copy method
 *  of the parent to ensure that all the attributes are really copied.
 *
 *  Nevertheless, some caution must be taken to avoid slicing problem
 *  as shown in the following example.
 *
 *  Example:
 *  \code
 *  class xyzView : public dtkAbstractView
 *  {
 *    ...
 *    void copy(const dtkAbstractObject& other);
 *    ...
 *  };
 *
 *  void xyzView::copy(const dtkAbstractObject& other)
 *  {
 *     // copy of the parent attributes
 *     dtkAbstractView::copy(other);
 *
 *     // copy of the xyzView attributes
 *     if (other.identifier() == this->identifier()) {
 *        // cast other into xyzView and do the copy
 *     } else {
 *        dtkWarn() << "other is not of same type than this, slicing is occuring.";
 *     }
 *  }
 *  \endcode
