I'm looking to create an iterator which iterates over two joined ranges:
[b0,e0)[b1,e1)
I'm sure there's a way to do it with an iterator adapter. I was wondering, however, if someone knew of an already available implementation.
Are both pairs of iterators always the same type?

Good point, thanks. Here's the exact situation I have: // mf of a class which derives from super_type // which prepends 1 to one of the arguments before calling // the super's (protected) mf template<typename R0,typename R1> void mf( const R0& source, const R1& rest_weight ){ typedef std::vector<value_type> weight_type; typedef boost::range_iterator<weight_type> ri_type; typedef typename ri_type::type iter_type; typedef typename iterator_difference<iter_type>::type diff_type; //TODO joined iterator preferable static weight_type weight(this->weight_size,(value_type)(1)); iter_type i = boost::begin(weight); std::advance(i,(diff_type)(1)); copy( boost::begin(rest_weight), boost::end(rest_weight), i ); super_type::mf( source, weight); //args passed by const ref as well }
