在某些情况下,使用私有构造函数对类进行反序列化不适用于Boost 1.58.在1.57它工作得很好.使用Visual Studio 2013编译时,下面的代码提供以下错误消息.
错误信息：
1> SerializeTest.cpp 1>c:\program files (x86)\vc\include\xmemory0(588): error C2248: 'A::A' : cannot access private member declared in class 'A' 1> c:\projects\serializetest\serializetest.cpp(14) : see declaration of 'A::A' 1> c:\projects\serializetest\serializetest.cpp(9) : see declaration of 'A'
码：
#include <boost/archive/text_iarchive.hpp>
#include <boost/archive/text_oarchive.hpp>
#include <boost/serialization/serialization.hpp>
#include <boost/serialization/vector.hpp>
#include <vector>
#include <sstream>
class A
{
public:
A(int i) {}
private:
A() {}
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive& ar,const unsigned int version)
{
}
};
class B
{
public:
B() {}
private:
std::vector<A> m_a;
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive& ar,const unsigned int version)
{
ar & BOOST_SERIALIZATION_NVP(m_a);
}
};
int main(int argc,char* argv[])
{
std::ostringstream os;
boost::archive::text_oarchive oa(os);
{
B b;
oa & b;
}
{
std::stringstream myIstream;
myIstream.write(os.str().c_str(),os.str().length());
boost::archive::text_iarchive ia(myIstream);
B b;
ia >> b;
}
return 0;
}
这是Boost回归还是我的疏忽？
