类名称：Filter
方法名：batchFinished

Filter.batchFinished介绍

[英]Signify that this batch of input to the filter is finished. If the filter requires all instances prior to filtering, output() may now be called to retrieve the filtered instances. Any subsequent instances filtered should be filtered based on setting obtained from the first batch (unless the inputFormat has been re-assigned or new options have been set). This default implementation assumes all instance processing occurs during inputFormat() and input().
[中]表示过滤器的这批输入已完成。如果过滤器在过滤之前需要所有实例，现在可以调用output（）来检索过滤后的实例。应根据从第一批获得的设置筛选筛选任何后续筛选实例（除非重新分配了inputFormat或设置了新选项）。此默认实现假定所有实例处理都发生在inputFormat（）和input（）期间。
