方法的具体详情如下:
包路径:org.matsim.core.utils.io.IOUtils
类名称:IOUtils
方法名:getInputStream
[英]Tries to open the specified file for reading and returns an InputStream for it. Supports gzip-compressed files, such files are automatically decompressed. If the file is not found, a gzip-compressed version of the file with the added ending ".gz" will be searched for and used if found.
[中]尝试打开指定的文件进行读取,并为其返回InputStream。支持gzip压缩文件,此类文件会自动解压缩。如果找不到该文件,将搜索并使用添加了结尾“.gz”的gzip压缩版本的文件。
