[Quantity-devel] replace function in VariableVector

[Kai L. <km...@us...>]

Bernd,

I propose the following function in the
VariableVector class:

//! replace the element at position index
   template<template<class, class> class Q1, class GT1, class Head1,
                            class Tail1, class DU1, class U1, class DT1>
   void replace (const int index, const Q1<Quantity<GT1,
		 Typelist<Head1, Tail1>, DU1, DT1>, U1> &new_quantity)
    {
      if (index >=3D 0 && index < length ())
      {
	values[index] =3D
	  Unit::Reverse(CheckAgainstAllUnits<typename Q1<Quantity<GT1,
			Typelist<Head1, Tail1>, DU1, DT1>, U1>::Unit,
			typename TL::Append<Typelist<Head, Tail>,
			NonPrefixable<typename Q1<Quantity<GT1,
			Typelist<Head1, Tail1>, DU1, DT1>, U1>::Type,
			GenericUnit, DT>
			>::Result >::RET::Standard
			(new_quantity.raw_value()));
      }
      else
      {throw QuantityVectorOutOfBounds();}
    }
