Re: [Boost-users] multi_index_container for composite key

Thanks for the reply.. Let me put my requirement more clear. I want to loop through and get all the element Ids[ member] which are having the same member values[pid, orientX, orientY, orientZ, OffsetA and OffsetB]. I am expecting the count of the container to give the count of unique member entries. Something like: for (beambook::iterator iter = pb.begin(), i_end = pb.end(); iter != i_end; iter = pb.upper_bound(iter->eid)) { //print pid, orientX, orientY, orientZ, OffsetA, OffsetB VS VECTOR of eid's; } Thanks Uthpal -----Original Message----- From: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Andrew Holden Sent: Tuesday, June 01, 2010 7:10 PM To: boost-users@lists.boost.org Subject: Re: [Boost-users] multi_index_container for composite key On Tuesday, June 01, 2010 5:41 AM, Uthpal Urubail wrote:

Hi How could I loop through the container to get all the keys. Eg:       For(int i=0;i< beambook.count();++i) Or       Beambook:: iter1 = beambook.begin(), iter2 = beambook.end();

My requirement is to loop through the size and list compositeKey vs list of element Ids

beambook;

for (beambook::iterator iter = container.begin(), i_end = container.end(); iter != i_end; iter = container.upper_bound (get key from iter)) _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
