Serializing Boost.Tuple
Hi,
Just thought I would share some code that serializes Boost.Tuple using
Boost.Serialization:
#include
Is there any plan to include this code to a tuple header?
tuple_serialization.hpp ?

Hi,
Just thought I would share some code that serializes Boost.Tuple using Boost.Serialization:
#include
#include #include namespace boost { namespace serialization {
#define GENERATE_ELEMENT_SERIALIZE(z,which,unused) \ ar & boost::serialization::make_nvp("element",t.get< which >());
#define GENERATE_TUPLE_SERIALIZE(z,nargs,unused) \ template< typename Archive, BOOST_PP_ENUM_PARAMS(nargs,typename T) > \ void serialize(Archive & ar, \ boost::tuple< BOOST_PP_ENUM_PARAMS(nargs,T) > & t, \ const unsigned int version) \ { \ BOOST_PP_REPEAT_FROM_TO(0,nargs,GENERATE_ELEMENT_SERIALIZE,~) \ }
BOOST_PP_REPEAT_FROM_TO(1,10,GENERATE_TUPLE_SERIALIZE,~);
}}
It does not handle 0-element tuples (not sure that it should, actually!) Kudos to the insanity that produced Boost.Preprocessor.

I think the best way to get it looked at would be to file a bug.
Anyway, if there was an is_tuple<T> metafunction, there would be a more
elegant way to do it:
// not compiled or tested
namespace boost { namespace serialization {
template

Hmm, no I lied. You couldn't do it this way because then the overload would be ambiguous when it matched. I think... -- Sohail Somani http://uint32t.blogspot.com

Ambigous with what?

I see. With the free serialize function in boost::serialization namespace.

Ambiguous with the other boost::serialization::serialize function. I was
thinking of:
template
