本文整理了Java中org.apache.commons.io.FileUtils.directoryContains()方法的一些代码示例，展示了FileUtils.directoryContains()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。FileUtils.directoryContains()方法的具体详情如下：
包路径：org.apache.commons.io.FileUtils
类名称：FileUtils
方法名：directoryContains

FileUtils.directoryContains介绍

[英]Determines whether the parent directory contains the child element (a file or directory).

Files are normalized before comparison.

Edge cases:

  • A directory must not be null: if null, throw IllegalArgumentException
  • A directory must be a directory: if not a directory, throw IllegalArgumentException
  • A directory does not contain itself: return false
  • A null child file is not contained in any parent: return false
    [中]确定父目录是否包含子元素（文件或目录）。
    文件在比较之前被规范化。
    边缘情况：
    *目录不能为null：如果为null，则抛出IllegalArgumentException
    *目录必须是目录：如果不是目录，则抛出IllegalArgumentException
    *目录不包含自身：返回false
    *任何父级中都不包含空的子文件：返回false

代码示例

private boolean isOptimisticDirectoryContainsFile(final File directory,
                         final File child) {
  try {
    return FileUtils.directoryContains(directory, child);
  } catch (IOException cause) {
    // 如果这里能抛出异常，则说明directory或者child发生损坏
    // 需要返回TRUE以此作乐观推断，出错的情况也属于当前目录
    // 这个逻辑没毛病,主要是用来应对USER目录被删除引起IOException的情况
    logger.debug("occur OptimisticDirectoryContainsFile: directory={} or child={} maybe broken.", directory, child, cause);
    return true;
  }
}
