包路径：org.matsim.core.utils.io.IOUtils
类名称：IOUtils
方法名：getOutputStream

IOUtils.getOutputStream介绍

[英]Returns a buffered and optionally gzip-compressed output stream to the specified file. If the given filename ends with ".gz", the written file content will be automatically compressed with the gzip-algorithm.
[中]将缓冲和可选的gzip压缩输出流返回到指定文件。如果给定的文件名以“.gz”结尾，则写入的文件内容将使用gzip算法自动压缩。
