834 "\n\n"
835 "A concrete example would be the 'Function' class. It declares "
836 "the existence of 'value()' and 'gradient()' member functions, "
837 "and both are marked as 'virtual'. Derived classes have to "
838 "override these functions for the values and gradients of a "
839 "particular function. On the other hand, not every function "
840 "has a gradient, and even for those that do, not every program "
841 "actually needs to evaluate it. Consequently, there is no "
842 "*requirement* that a derived class actually override the "
843 "'gradient()' function (as there would be had it been marked "
844 "as abstract). But, since the base class cannot know how to "
845 "compute the gradient, if a derived class does not override "
846 "the 'gradient()' function and it is called anyway, then the "
847 "default implementation in the base class will simply throw "
848 "an exception."
849 "\n\n"

851 "one just illustrated. To fix the problem, you need to "
