Re: [Boost-users] Is there such stuff in boost?

Hi all

I'm wondering if there is such stuff in boost, or anything similar:

double d0, d1, d2, d3; boost::array array = {{d0, d1, d2, d3}}; for(int i=0; i<4; i++) array[i] = i; assert(d2 == 2);

or

double d0, d1, d2, d3; boost::array array; boost::bind(array[0], d0); boost::bind(array[1], d1); boost::bind(array[2], d2); boost::bind(array[3], d3); for(int i=0; i<4; i++) array[i] = i; assert(d2 == 2);

Sounds like you need the reference wrappers http://www.boost.org/doc/libs/1_35_0/doc/html/ref.html which are designed for passing references to function objects where passing a value would be inappropriate or inefficient, as they are CopyConstructible and Assignable they are also suitable for storage in containers where simple pointers are inappropriate.

Thanks Max

Thank you Somerville for your direction. I never used Ref before, and I'll have a look into its documentation. If it won't take a long time, is it possible to rewrite the above code snnipet making use of boost.Ref? Thanks again. Max
