Hello,
I have a Foo class and I can serialize it with JsonSerializer class :
{"integer":1,"str":"str1"}
Now, I want to add an extra field ("other" for example) :
{"integer":1,"str":"str1", other: "10.5"}
How can I do that ?
Thanks,
Jean-Michel
#include <iostream>
#include <sstream>
#include <cxxtools/jsonserializer.h>
#include <cxxtools/jsondeserializer.h>
class Foo {
public:
int integer;
std::string str;
};
void operator<<= (cxxtools::SerializationInfo& si, const Foo& obj)
{
si.addMember("integer") <<= obj.integer;
si.addMember("str") <<= obj.str;
}
void operator>>= (const cxxtools::SerializationInfo& si, Foo& obj)
{
si.getMember("integer") >>= obj.integer;
si.getMember("str") >>= obj.str;
}
int main()
{
{
std::stringstream is;
Foo foo1;
foo1.integer = 1;
foo1.str = "str1";
cxxtools::JsonSerializer s(is);
s.serialize(foo1);
// HOWTO TO ADD ANOTHER FIELD ?
"other" = 10.5;
s.finish();
std::cout << is.str() << std::endl;
}
return 0;
}
Just add it into your class and serialization operator:
class Foo {
public:
int integer;
std::string str;
std::string other;
};
void operator<<= (cxxtools::SerializationInfo& si, const Foo& obj)
{
si.addMember("integer") <<= obj.integer;
si.addMember("str") <<= obj.str;
si.addMember("other") <<= obj.other;
}
void operator>>= (const cxxtools::SerializationInfo& si, Foo& obj)
{
si.getMember("integer") >>= obj.integer;
si.getMember("str") >>= obj.str;
si.getMember("other") >>= obj.other;
}
You can't modify the generated json string afterwords.
Btw. You can serialize to cout directly and may want to use beautify for
debugging like this:
cxxtools::JsonSerializer s(std::cout);
s.beautify(true);
s.serialize(foo1);
s.finish();
