having an alternate function based on some trait .. exactly how to do

HI,
  i have a class like this (simplified version)
  template<typename C>
  class range_view{
    public: /// all of the container typedefs.
      iterator begin(){
        return cont_.begin()+range_.first;
      }
      iterator end(){
        return cont_.begin()+range_.second;
      }
    private:
     C* cont_;
    std::pait<size_type,size_type> range_;
  };

now i want to handle begin & end different way some container. At
present i copied it again written as,

template<typename C, typename M = C::remove_aware>
  class range_view{
    public: /// all of the container typedefs.
      iterator begin(){
        return cont_->begin()+range_.first+cont_->remove_count();
      }
      iterator end(){
        return cont_->begin()+range_.second+cont_->remove_count();
      }
    private:
     C* cont_;
    std::pait<size_type,size_type> range_;
  };
so, instead of having a full class for a remove aware container, i
want just begin & end should match with the trait...
anyways can it be done using SFINAE  ?
thanks
