Re: [boost] [multi_index] composite keys: request for advice

From: Joaquin M Lopez Munoz <joaquin@tid.es>

Composite keys can be specified by a new construct called composite_key in the following manner:

struct record { int first; int second int third; };

multi_index_container< record, indexed_by< composite_key< record, //base value member<record,int,&record::first>, // first key

Would that you could make this work to avoid the duplication and chance for errors: member< &record::first > I know a function template can deduce the other types, but I can't think of how to make it work here. -- Rob Stewart stewart@sig.com Software Engineer http://www.sig.com Susquehanna International Group, LLP using std::disclaimer;
