更正重写的QDataStream运算符和链接问题

Question

我需要覆盖>>和<lt；QDataStream的运算符。这是我的代码：

QDataStream &operator <<(QDataStream &out, const SScenarioEntry Entry)
{
    out.writeRawData(Entry.EntryName, sizeof(Entry.EntryName));
    out << Entry.Number;
    out << Entry.Type;
    out.writeRawData(Entry.RequestString, sizeof(Entry.RequestString));
    out.writeRawData(Entry.AnswerString, sizeof(Entry.AnswerString));
    out.writeRawData(Entry.AdditionalParams, sizeof(Entry.AdditionalParams));
    out << Entry.Timeout;
    return out;
}
QDataStream &operator >>(QDataStream &in, SScenarioEntry Entry)
{
    in.readRawData(Entry.EntryName, sizeof(Entry.EntryName));
    in >> Entry.Number;
    in >> Entry.Type;
    in.readRawData(Entry.RequestString, sizeof(Entry.RequestString));
    in.readRawData(Entry.AnswerString, sizeof(Entry.AnswerString));
    in.readRawData(Entry.AdditionalParams, sizeof(Entry.AdditionalParams));
    in >> Entry.Timeout;
    return in;
}

在成功编译之后，我得到了一些错误，比如：

first define here
In function `Z7qt_noopv':
multiple definition of `operator>>(QDataStream&, scnent)`

我有两个问题：

1. 我必须如何定义<lt；和>>操作员正确工作
2. 如果这个代码是正确的，如何修复链接错误

这很奇怪，但通过划分函数公告和描述解决了问题。
