類的包裝嘗試：

把檢查與檢查非包裝出來，組合滿足業務需求就比較方便了。

1. 檢查某容器包含0

2. 不滿足時

...

// 檢查容器中元素是否滿足某種條件template <typename T>bool Check(T& container){    if (container.IsSatify())    {        return true;    }    return false;};// 基類：提供檢查接口class CCheckPRoc{public:    CCheckProc():m_pParent(nullptr){};    CCheckProc(CCheckProc& proc):m_pParent(&proc){};    virtual bool IsSatify() = 0;protected:    CIndexProc* m_pParent;};// 繼承類：提供檢查包含0的接口template <typename T>class CIncludeZero : public CCheckProc{public:    CIncludeZero(T& container):m_pContainer(&container)    {};    virtual bool IsSatify()    {        return m_pContainer->contains(0);    };private:    T* m_pContainer;};// 繼承類：提供檢查非的操作class CNotIn : public CCheckProc{public:    CNotIn(CCheckProc& proc):CCheckProc(proc){}    virtual bool IsSatify(int nIndex)    {        return !m_pParent->IsSatify(nIndex);    };};// 實例化函數，提供給外部使用bool IncludeZero(QList<int>& indexs ){    return Check(n, CIncludeZero<QList<int>>(indexs));}bool NotIncludedZero(QList<int>& indexs){    return Check(n, CNotIn(CIncludeZero<QList<int>>(indexs)));}
