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
