CObList::CObList

CObList( int nBlockSize = 10 );

参数：

nBlockSize

扩展列表所需的内存分配的粒度大小。

说明：
构造一个空CObject指针列表。当列表增大后，以nBlockSize为单位分配内存。若内存分配失败，那么将产生CMemoryException。

示例：
下面列出CObject派生类CAged，它用于所有收集示例中：
// Simple CObject-derived class for CObList examples
class CAge : public CObject
{
  DECLARE_SERIAL( CAge )
  private:
    int m_years;
  public:
    CAge() { m_years = 0; }
    CAge( int age ) { m_years = age; }
    CAge( const CAge& a ) { m_years = a.m_years; } // Copy constructor
    void Serialize( CArchive& ar);
    void AssertValid() const;
    const CAge& operator = ( const CAge& a )
    {
      m_years = a.m_years; return *this;
    }

    BOOL operator==(CAge a)
    {
      return m_years == a.m_years;
    }
    void* operator new(size_t nSize);
    void* operator new(size_t nSize, LPCSTR lpszFileName, int nLine);
    void operator delete(void* p);
    void operator delete(void* p, LPCSTR lpszFileName, int nLine);

    #ifdef _DEBUG
       void Dump( CDumpContext& dc ) const
       {
         CObject::Dump( dc );
         dc << m_years;
       }
    #endif
};

下面为CObList构造函数用法的例子：
CObList list( 20 ); // List on the stack with blocksize = 20.
CObList* plist = new CObList; // List on the heap with default blocksize.
