ROOT::Math::WrappedFunction< Func > Class Template Reference

template<typename Func = FreeFunctionPtr>
class ROOT::Math::WrappedFunction< Func >

Template class to wrap any C++ callable object which takes one argument i.e.

implementing operator() (double x) in a One-dimensional function interface. It provides a ROOT::Math::IGenFunction-like signature

Note: If you want to wrap just the reference (to avoid copying) you need to use Func& or const Func & as template parameter. The former should be used when the operator() is not a const method of Func
