Hallo,
I just wondered, why there is no possibility to serialize a unordered map. Since the STL map is serialized, i take the file for it and changed all maps to boost::unordered_map (multimap).
Or is there a better way, i just did not see?
Here is the code:
#ifndef BOOST_SERIALIZATION_UNORDEREDMAP_HPP
#define BOOST_SERIALIZATION_UNORDEREDMAP_HPP
// MS compatible compilers support #pragma once
#if defined(_MSC_VER) && (_MSC_VER >= 1020)
# pragma once
#endif
