Synopsis

This class is provided to enable compile time selection of the appropriate function call. Each template incarnation represent a function call interface definition.

Example

Float func(const Vector<Float>& x) {return x(0)*x(1);}        // x*y
// Convert C++ functions to Functionals
FunctionWrapper<Float> Func(func, 2);
