Detailed Description

template<class Problem>
class pism::taoutil::TaoGradientCallback< Problem >

Adaptor to connect a TAO objective gradient callback to a C++ object method.

The TAO library interfaces with user code via C-style callback functions. This class makes it convenient to associate a TAO Objective Gradient callback with a C++ object method. To assign

void MyObject::evaluateGradient(Tao tao,Vec x, Vec gradient);

as the objective function to a Tao tao,

MyObject obj;
TaoGradientCallback<MyObject>::connect(tao,obj);

The method name evaluateGradient for the callback is hard-coded. See TaoObjGradCallback for a technique to allow the method name to be specified (at the expense of a little more cumbersome code).
