  CObList( int nBlockSize = 10 );
 
  Parameter    Description
 
  <nBlockSize> The memory-allocation granularity for extending the list.
 
  Remarks
 
  Constructs an empty CObject pointer list. As the list grows, memory is
  allocated in units of <nBlockSize> entries. If a memory allocation
  fails, a CMemoryException is thrown.
 
  Example
 
  Below is a listing of the CObject-derived class CAge used in all the
  collection examples:
  // 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;
      }
   #ifdef _DEBUG
      void Dump( CDumpContext& dc ) const
      {
          CObject::Dump( dc );
          dc << m_years;
      }
   #endif
  };
 
  Below is an example of CObList constructor usage:
  CObList list( 20 );  // List on the stack with blocksize = 20
 
  CObList* plist = new CObList; // List on the heap with default blocksize
