基本类型的序列化和反序列化

#include "serializer.h"
#include &lt;iostream&gt;

//自定义类型需要重载操作符&gt;&gt;和&lt;&lt;
struct foo {
    int n;
    std::string str;
    foo() {}
    foo(int a, std::string s) 
        : n(a), str(s) {}
    friend Serializer&amp; operator&gt;&gt;(Serializer&amp; in, foo&amp; f)
    {
        in &gt;&gt; f.n &gt;&gt; f.str;
        return in;
    }
    friend Serializer&amp; operator&lt;&lt;(Serializer&amp; out, foo&amp; f)
    {
        out &lt;&lt; f.n &lt;&lt; f.str;
        return out;
    }
};

// 测试原生类型的序列化和反序列化
void test1()
{
    int a = 100;
    std::string c = "hello";
    Serializer sr;
    sr &lt;&lt; a;  //序列化
    sr &lt;&lt; c;

    int b = 0;
    std::string d;
    sr &gt;&gt; b; //反序列化
    sr &gt;&gt; d;
    std::cout &lt;&lt; "b=" &lt;&lt; b &lt;&lt; ", d=" &lt;&lt; d &lt;&lt; std::endl;
}

//测试自定义类型的序列化和反序列化
void test2()
{
    foo a(23, "evenleo");
    Serializer sr;
    sr &lt;&lt; a;

    foo b;
    sr &gt;&gt; b;
    std::cout &lt;&lt; "b.n=" &lt;&lt; b.n &lt;&lt; ", b.str=" &lt;&lt; b.str &lt;&lt; std::endl;
}
