Looking for someone's help me to make correct use of boost composite key. Requirement: Given config and type get all cid's Below example I am passing config =1; and type = 1; I am expecting all cid's matching both of them. i.e 1 and 2 only However if you see the out output it is: 1,2,3,1,8,3 //---------- #include <boost/multi_index_container.hpp> #include <boost/multi_index/ordered_index.hpp> #include <boost/multi_index/member.hpp> #include <boost/multi_index/composite_key.hpp> #include <iostream> #include <vector> struct record { unsigned int cid; unsigned int config; unsigned int type; //! default const.. record():cid(0),config(0),type(0){} //! parm. const.. record(unsigned int _cid, unsigned int _config, unsigned int _type): cid(_cid),config(_config),type(_type){} }; using boost::multi_index_container; using namespace boost::multi_index; typedef multi_index_container< record, indexed_by< ordered_non_unique< composite_key< record, member<record,unsigned int,&record::config>, member<record,unsigned int,&record::type> > > >
recordBookDef;
recordBookDef recordbook; int main() { record obj1(1,1,1); record obj2(2,2,1); record obj3(3,3,1); recordbook.insert(obj1); recordbook.insert(obj2); recordbook.insert(obj3); record obj11(2,1,1); record obj12(1,2,1); record obj13(8,2,1); recordbook.insert(obj11); recordbook.insert(obj12); recordbook.insert(obj13); unsigned int config =1; unsigned int type = 1; recordBookDef::iterator it=recordbook.find(boost::make_tuple(config,type)); while(it!=recordbook.end()) { //if(it->config == 1) std::cout<<it->config<<","; ++it; } std::cout<<std::endl; return 0; } Regards, UJ
