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

Filter.setInputFormat介绍

[英]Sets the format of the input instances. If the filter is able to determine the output format before seeing any input instances, it does so here. This default implementation clears the output format and output queue, and the new batch flag is set. Overriders should call super.setInputFormat(Instances)
[中]设置输入实例的格式。如果过滤器能够在看到任何输入实例之前确定输出格式，那么它将在此处执行此操作。此默认实现清除输出格式和输出队列，并设置新的批标记。重写器应调用super.setInputFormat(Instances)
