By using the for clause in the after-aggregation detail filter on a non-projected data item, the underlying query automatically projects and groups the item as the outer most column of the list.
通过在一个未投射的数据项上的after - aggregation细节过滤器中使用for子句，底层查询会自动将该项目投射并分组为列表的最外层列。
In this scenario, the list object will need to be associated to a new master query which consists of only the Product line data item with no summary filter.
在这个场景中，列表对象需要关联到一个新的主查询，该查询只包含没有摘要过滤器的Productline数据项。
The filter method in Listing 9 accepts a list and a criteria (a code block specifying how to filter the list) and iterates over the list, adding each item to a new list if it matches the predicate.
清单9中的filter方法接受了一个list和一个criteria(指定如何过滤列表的代码块)并对列表进行遍历，将满足谓语的项添加到一个新列表中。
