术语 | CArchive::operator 3d3d |
释义 | CArchive::operator >> friend CArchive& operator >>(CArchive& ar, CObject* pOb); throw (CArchiveException,CFileException,CMemoryException); friend CArchive& operator >>(CArchive& ar,const CObject* pOb); throw (CArchiveException,CFileException,CMemoryException); CArchive& operator >>(BYTE& by); throw (CArchiveException,CFileException); CArchive& operator >>(WORD& w); throw (CArchiveException,CFileException); CArchive& operator >>(int& i); throw (CArchiveException,CFileException); CArchive& operator >>(LONG& l); throw (CArchiveException,CFileException); CArchive& operator >>(DWORD& dw); throw (CArchiveException,CFileException); CArchive& operator >>(float& f); throw (CArchiveException,CFileException); CArchive& operator >>(double& d); throw (CArchiveException,CFileException); 返回值: 可使多个插入运算符在一行上的CArchive参考。 说明: 由归档文件装载确定的对象或主要类型。 如果在类的实现中使用IMPLEMENT_SERIAL宏,然后重载CObject的提取运算符调用被保护的ReadObject函数(带有一个非零的运行时指针)。此函数反过来调用类的Serialize函数。 示例: int i; extern CArchive ar; if(ar.IsLoading( )) ar>>i; 请参阅:CArchive::ReadObject, CObject::Serialize |
