本文整理了Java中org.apache.jena.tdb.base.file.Location.getPath()方法的一些代码示例，展示了Location.getPath()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Location.getPath()方法的具体详情如下：
包路径：org.apache.jena.tdb.base.file.Location
类名称：Location
方法名：getPath

Location.getPath介绍

[英]Return the name of the file relative to this location
[中]返回相对于此位置的文件名
