The items in the rowColumns list will become data members of classes of this type when they are created by the Reflector.
|
|
|
type: Content of: <html><body><p>
|
|
|
|
|
当我们使用 Reflector 创建该类时，所有在列名列表（rowColumns）中的各项将会成为该类的一个数据成员（data members）。

The initialization phase builds the SQL for the database interactions. It uses the system catalogs of the database to do this, but requires some basic information to get started. The class attributes of the classes derived from RowClass are used for this. Those classes are passed to a Reflector when it is created.

在初始化的阶段，会建立一些 SQL 操作来和数据库进行互交。她使用到了数据库的系统目录，同时需要的还有另外一些基本信息。派生自 RowClass 的子类的类属性的作用便是提供这些信息。这些子类在创建的时候会被传入一个Reflector进行处理。
