Hi List,
Below is a small test program derived from the cxxtools demo
serialization.cpp which serializes in binary to a file and reads the
information back in. This works perfectly fine and outputs "HelloWorld".
If however I change the serialization operators definition to use
unnamed array members (source at the end) as pointed out by Tommy in
http://sourceforge.net/p/tntnet/mailman/message/32265732/ an error is
produced:
"unknown serialization type code <7f>"
In cxxtools/bin/serializer.h this code is actually defined as
TypePlainOther but does not seem to be processed in the parser.
I am unsure if this is a bug, or if it is simply my deserialization
operator, that is badly defined.
Thanks for your input,
Michael
Working program (compile with: g++ <filename> -lcxxtools -lcxxtools-bin)
#include <iostream>
#include <fstream>
#include <cxxtools/bin/bin.h>
class Object
{
friend void operator>>= (const cxxtools::SerializationInfo& si,
Object& object);
std::string _stringValue;
int _intValue;
public:
Object()
: _intValue(0)
{ }
Object(const std::string& stringValue, int intValue)
: _stringValue(stringValue),
_intValue(intValue)
{ }
const std::string& stringValue() const
{ return _stringValue; }
int intValue() const
{ return _intValue; }
};
void operator<<= (cxxtools::SerializationInfo& si, const Object& object)
{
si.setTypeName("Object");
si.addMember("stringValue") <<= object.stringValue();
si.addMember("intValue") <<= object.intValue();
}
void operator>>= (const cxxtools::SerializationInfo& si, Object& object)
{
si.getMember("stringValue") >>= object._stringValue;
si.getMember("intValue") >>= object._intValue;
}
int main(int argc, char* argv[])
{
try
{
std::vector<Object> objects;
objects.push_back(Object("Hello", 42));
objects.push_back(Object("World", -17));
std::ofstream outfile("file.bin");
outfile << cxxtools::bin::Bin(objects);
outfile.close();
objects.clear();
std::ifstream infile("file.bin");
cxxtools::bin::Deserializer deserializer(infile);
deserializer.deserialize(objects);
std::cout << objects[0].stringValue() << objects[1].stringValue() <<
std::endl;
}
catch (const std::exception& e)
{
std::cerr << e.what() << std::endl;
}
}
