Re: [Boost-users] boost::multi_index

Thanks for your answer Igor. Unfortunately that is out of my control. This is the type of structure we used across multiple applications. I was checking key extractors and I think that might work but haven't tried out yet. Thanks Priyank On Apr 6, 2011, at 3:32 PM, "Igor R" wrote:

Hello,

I have a question regarding creating composite key/specifying length for arrays while using multi_index container based on following structure.

struct TestStruct {

char firstKey[50];

char secondKeyPart[3];

uint32_t thirdKeyPart;

……Some other information….

};

Do I really read to specify this lengths for character arrays? If yes, how do I do that while specifying key parts as below?

typedef multi_index_container <

TestStruct,

indexed_by<

//non-unique as some subscribers might have more than one number

hashed_unique<

composite_key<

TestStruct,

member,

member,

The above keys will hash the pointer values, which is probably not what you want. If you change plain C arrays to std::string, it will work as you expect. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
