Friend QDataStream from within NameSpace

[stevenceuppens]

Hi All,

I want to use the QDataStream operators on a custom class.

My class is within it's own namespace, which makes the friend declaration of this QDataStream operators faling...

if i try to acces the private member "m_name" from within the QDataStream operators, it's not working, compiler is complaining that m_name is a private member.

if i remove the namespace declaration "MyNameSpace", all is working fine..

.h file
@
#include <QtCore/QString>

namespace MyNameSpace {

class MyClass
{
public:
MyClass();
~MyClass();

public:
inline QString name() const { return m_name; }

public:
friend QDataStream &operator <<(QDataStream &out, const MyClass &class);
friend QDataStream &operator >>(QDataStream &in, MyClass &class);

private:
QString m_name;
};

QDataStream &operator <<(QDataStream &out, const MyClass &class);
QDataStream &operator >>(QDataStream &in, MyClass &class);

}
@

.cpp file @
using namespace MyNameSpace;

MyClass::MyClass()
{}

MyClass::~MyClass()
{}

QDataStream &operator <<(QDataStream &out, const MyClass &class)
{
return out << class.m_name;
}

QDataStream &operator >>(QDataStream &in, MyClass &class)
{
return in >> class.m_name;
}

Hi,

You have two options:

surround the operators implementation with your namespace

prefix the operators with your namespace
