ROOT::Math::WrappedMemFunction< FuncObj, MemFuncPtr > Class Template Reference

template<typename FuncObj, typename MemFuncPtr>
class ROOT::Math::WrappedMemFunction< FuncObj, MemFuncPtr >

Template class to wrap any member function of a class taking a double and returning a double in a 1D function interface For example, if you have a class like: struct X { double Eval(double x); }; you can wrapped in the following way: WrappedMemFunction<X, double ( X::* ) (double) > f;.
