Re: [Boost-users] [Serialization] Non-default constructor and template class

Hi Kurt, you should be able to simply define a private default constructor, if boost::serialization::acess is declared as a friend of your class. There is no need to initialize variables that are in your serialize() function, as Boost.Serialization should set their values after default construction. So in most cases the default constructor may be empty and is trivial to implement, while it can not be called by any external entity (except if it is also declared „friend“). Kind Regards, Beet

I am attempting to serialize a template class without a default constructor, so I am overriding boost::serialization::save_construct_data(). I'm not sure of the correct syntax to declare that function. The line marked below fails to compile with a "too many template-parameter-lists" error.

// Forward declaration of my class template class HashMap;

namespace boost { namespace serialization {

template<class Archive> template void save_construct_data(Archive &ar, const HashMap< Key, Value, Hasher > *t, const unsigned int file_version); // error here }}

Thanks for any help, Kurt
