Detailed Description

compute the cartesian product of many set

Parameters

MultiSet

must be of the following form vector< vector< ElementaryType1, ElementaryType2,... > , vector< ...ElementaryTypes...> ... > where Elementary types are not boost::mpl::Container : i.e int, classes, std::vector<int> etc...

Example

 using namespace boost::mpl;

 typedef vector< vector<signed char, signed short, signed int>,  vector< float, double >  , vector< std::string,
unsigned char >   > ::type MultiSet;

 typedef apply< CartesianProduct, MultiSet>::type Result;

 BOOST_MPL_ASSERT_RELATION( size< Result >::value , == , 12 );

 BOOST_MPL_ASSERT(( equal<  at_c<Result,0>::type, vector<  signed char,  float  , std::string >    > ));
 BOOST_MPL_ASSERT(( equal<  at_c<Result,1>::type, vector<  signed char,  float  , unsigned char >    > ));
 BOOST_MPL_ASSERT(( equal<  at_c<Result,2>::type, vector<  signed char,  double , std::string >    > ));
 BOOST_MPL_ASSERT(( equal<  at_c<Result,3>::type, vector<  signed char,  double , unsigned char >    > ));

 BOOST_MPL_ASSERT(( equal<  at_c<Result,4>::type, vector< signed short,  float  , std::string >    > ));
 BOOST_MPL_ASSERT(( equal<  at_c<Result,5>::type, vector< signed short,  float  , unsigned char >    > ));
 BOOST_MPL_ASSERT(( equal<  at_c<Result,6>::type, vector< signed short,  double , std::string >    > ));
 BOOST_MPL_ASSERT(( equal<  at_c<Result,7>::type, vector< signed short,  double , unsigned char >    > ));

 BOOST_MPL_ASSERT(( equal<  at_c<Result,8>::type, vector<  signed int,  float  , std::string >    > ));
 BOOST_MPL_ASSERT(( equal<  at_c<Result,9>::type, vector<  signed int,  float  , unsigned char >    > ));
 BOOST_MPL_ASSERT(( equal<  at_c<Result,10>::type, vector< signed int,  double , std::string >    > ));
 BOOST_MPL_ASSERT(( equal<  at_c<Result,11>::type, vector< signed int,  double , unsigned char >    > ));
