Tommi,
sometimes it is useful to access JSON or XML fields
without a dedicated serialization structure.
SerializationInfo is convenient for that, but I don't see a way
to use it outside of serialization:
when I use cxxtools::xml::XmlDeserializer::si or
cxxtools::xml::XmlDeserializer::current the application crashes.
I have found a workaround using C++ lambdas:
struct FunctionOverSerializationInfo {
std::function<void (const cxxtools::SerializationInfo&)> _fun;
FunctionOverSerializationInfo (std::function<void (const
cxxtools::SerializationInfo&)> fun): _fun (fun) {}
};
void operator>>= (const cxxtools::SerializationInfo& si,
FunctionOverSerializationInfo fosi) {
fosi._fun (si);
}
std::ifstream is ("file");
cxxtools::xml::XmlDeserializer ds (is);
FunctionOverSerializationInfo dsFun (
[&](const cxxtools::SerializationInfo& si) {
// Use `si` there.
}
);
ds.toObject (is, dsFun);
But is there a more direct way of using SerializationInfo
outside of object deserialization?
