C++ virtual继承

由于懒画图引用别人的一个，请大家原谅，谢谢理解：

class CBase
{
public:
    CBase(unsigned int len) : m_buffer(0)
    {
       if(len > 0)
       {
           m_buffer = new char[len];
       } 
    }

    ~CBase
    {
       if(NULL != m_buffer)
       {
          delete [] m_buffer;
          m_buffer = NULL;
       }
    }

private:
    char* m_buffer;
};

</pre><pre name="code" class="cpp">class Test1 : public virtual CBase
{
public:
//...
};

class Test2 : public virtual CBase
{
public:
//...
};

class Test3 : public Test1, public Test2
{
public:
//...
};
