Re: [Boost-users] multi_array index_gen or extent_gen store for reuse

Levent wrote:

Is it possible to store tuples of index or range values (or generators) for later reuse? Consider the following:

typedef boost::multi_array Arr; typedef Arr::index_range Ir; typedef ??? indices; Arr a(boost::extents[3][4][5]); Arr b(a); indices somerange = Arr::index_gen[Ir()][Ir(1,5)][Ir()<2]; b[somerange] = a[somerange]; // and so on

What should `???' be?

thanks - Levent

it seems one answer is typedef boost::detail::multi_array::index_gen<3,3> indices; but is there anything as a part of the user interface?
