本文整理了Java中org.osgi.framework.Bundle.getDataFile()方法的一些代码示例，展示了Bundle.getDataFile()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。Bundle.getDataFile()方法的具体详情如下：
包路径：org.osgi.framework.Bundle
类名称：Bundle
方法名：getDataFile

Bundle.getDataFile介绍

[英]Creates a File object for a file in the persistent storage area provided for this bundle by the Framework. This method will return null if the platform does not have file system support or this bundle is a fragment bundle.

A File object for the base directory of the persistent storage area provided for this bundle by the Framework can be obtained by calling this method with an empty string as filename.

If the Java Runtime Environment supports permissions, the Framework will ensure that this bundle has the java.io.FilePermission with actions read, write, delete for all files (recursively) in the persistent storage area provided for this bundle.
[中]为框架为此捆绑包提供的持久存储区域中的文件创建文件对象。如果平台没有文件系统支持，或者此捆绑包是片段捆绑包，则此方法将返回null。
通过使用空字符串作为文件名调用此方法，可以获得框架为此捆绑包提供的持久存储区域的基本目录的文件对象。
如果Java运行时环境支持权限，框架将确保此捆绑包具有Java权限。木卫一。FilePermission，对该捆绑包提供的持久存储区域中的所有文件执行读取、写入、删除（递归）操作。
