As I covered in the last column, signatures are an item added to the class file format by generics; only references to generic types have signatures.

正如我在前一期中介绍的，签名是泛型添加到类文件格式中的项目；只有对泛型的引用才有签名。

youdao

In this above code, even if the Order or Item class is mapped with an annotation, a separate XML file, or not at all (I would then have to map each field), I can still override it with this XML.

在上面的代码中，即使使用注释、单独的XML文件或不使用任何内容(必须映射每个字段)来映射order或item类，我仍能够使用此X ML覆盖它。

To return to the original file, select the appropariate menu item or button ("Revert to original class file").

选中合适的菜单项或者按钮， 返回原始的文件。
