Walking the results is a simple exercise in using the Iterator interface implemented by ObjectSet.
使用由objectset实现的Iterator接口遍历结果非常简单。
Once that's all done, I call get() on the db4o database and check to see if the ObjectSet returned contains any objects. This gives me a basic method outline that looks like the one shown in Listing 6
完成这些操作后，对db4o数据库调用get()并查看返回的ObjectSet是否包含任何对象。
