Detailed Description

template<class Problem, void(Problem::*)(Tao, Vec, double *, Vec) Callback>
class pism::taoutil::TaoObjGradCallback< Problem, Callback >

Adaptor to connect a TAO objective and gradient function 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 combined objective value and gradient callback with a C++ object method. To assign

void MyObject::someObjectiveFunction(Tao tao,Vec x, double *value, Vec gradient);

as the convergence test function to a Tao tao,

MyObject obj;
typedef TaoObjGradCallback<MyObject,&MyObject::someObjectiveFunction> ObjGradCallback;
ObjGradCallback::connect(tao,obj);

Note that the method name for the callback must be specified explicitly via a template argument.
