本文整理了Java中org.eclipse.core.filesystem.EFS类的一些代码示例，展示了EFS类的具体用法。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。EFS类的具体详情如下：
包路径：org.eclipse.core.filesystem.EFS
类名称：EFS

EFS介绍

[英]This class is the main entry point for clients of the Eclipse file system API. This class has factory methods for obtaining instances of file systems and file stores, and provides constants for option values and error codes.
[中]此类是Eclipse文件系统API客户端的主要入口点。此类具有用于获取文件系统和文件存储实例的工厂方法，并为选项值和错误代码提供常量。

/**
 * Returns a string representation of a URI suitable for displaying to an end user.
 */

  } catch (CoreException e) {
    //there is no store defined, so the best we can do is the URI toString.
    return uri.toString();
  }
