Thank you very much for the fast reply,
If i have no problem adding a function that returns the value to sort by (e.g. long GetClientId) and i use BOOST_MULTI_INDEX_CONST_MEM_FUN define key extractor.
Would you suggest i use BOOST_MULTI_INDEX_CONST_MEM_FUN,write my own custom key extractor or it does not matter in terms of performance (or anythingelse)?
From the point of view of performance there shouldn't be any difference between both approaches. So I guess it's a matter of taste; I'd go for the custom extractor if using BOOST_MULTI_INDEX_CONST_MEM_FUN somehow forces you to change the design of your class or looks forced.
