用template实现的Adapter

class Class1
{
public:
    Class1(int c) : m_count(c)
    {
        PRINT;
    }
    void proc()
    {
        PRINT;
    }
private:
    int m_count;
};
class Class2
{
public:
    Class2(const string& name): m_name(name)
    {
        PRINT;
    }
    void proc()
    {
        PRINT;
    }
private:
    string m_name;
};

class IAdapter
{
public:
    virtual ~IAdapter() {}
    virtual void proc() = 0;
};
template<typename T>
class Adapter: public IAdapter, private T
{
public:
    Adapter(int c): T(c)
    {
        PRINT;
    }
    Adapter(const string& name) :T(name)
    {
        PRINT;
    }
    void proc()
    {
        T::proc();
    }
};
