     116 *  \subsection serialization-important notes Some important notes
    116117 *
    117  * \date 2011-10-31
     118 *  There are a few things that one needs to be aware of: Otherwise easily
     119 *  a stupid mistake is introduced that is trivial once understand but hard
     120 *  to find otherwise. This is especially so because compiler errors with
     121 *  respect to the serialization part are always length (whole page) and
     122 *  very hard to read:
     123 *  \li Always obtain the same type from an archive that you put into it!
     124 *    If it's been an instance, get an instance, not a ref(&) or a pointer(*)
     125 *    and also the other way round.
     126 *  \li boost::serialization always uses the default constructor of your class
     127 *    that is afterwards filled with state information stored. If your default
     128 *    constructor is unusable, something goes wrong here. There are two ways
     129 *    out:
     130 *    -# Write a private default constructor. Also you might have to split
     131 *      serialize() into load() and save() and do some additional stuff in
     132 *      load().
     133 *    -# one can write save_construct_data() and load_construct_data() directly
     134 *      as is explained in the boost::serialization documentation on
     135 *      constructors (as of 1.47).
     136 *  \li Const members are a problem as they can only be written during the
     137 *    constructor and as always the default cstor is used ... however, wiggle
     138 *    around by casting it to non-const, e.g.
     139 *    \code
     140 *    const foo foo_instance;
     141 *    ...
     142 *    const_cast<foo &>(foo_instance);
     143 *    \endcode
     144 *    Alternatively, you could place const variables in an extra class (and
     145 *    non-const there), make them available only via a getter. Hence, they
     146 *    would still be const in your main class but could be serialized without
     147 *    any trouble.
     148 *  \li When you want to serialize a derived class, also the base class state
     149 *    has to be serialized, this is done via
     150 *    \code
     151 *    boost::serialization::base_object<base type>(*this);
     152 *    \endcode
     153 *
