包路径：weka.filters.Filter
类名称：Filter
方法名：getOutputFormat

Filter.getOutputFormat介绍

[英]Gets the format of the output instances. This should only be called after input() or batchFinished() has returned true. The relation name of the output instances should be changed to reflect the action of the filter (eg: add the filter name and options).
[中]获取输出实例的格式。只有在input（）或batchFinished（）返回true后才应调用此函数。应该更改输出实例的关系名称以反映筛选器的操作（例如：添加筛选器名称和选项）。
