1·In some situations, you can use the Preferred Data Source Pattern recursively.
在某些情况下，您可以递归地使用首选数据源模式。
2·Imagine a scenario in which you want to traverse a directory tree recursively, stopping at each file and directory under that tree and having your own callback methods invoked for each entry found.
设想一个场景，您想要递归地访问一个目录树，在该树中的每个文件及目录上停下来，并为每个查找到的条目调用您自己的回调方法。
3·If your program walks the file system, recursively iterating through subdirectories, be careful if an attacker could ever manipulate the directory structure you're walking.
如果您的程序需要遍历文件系统(递归地遍历子目录)，那么要提防攻击者可能会利用您正在遍历的目录结构。
4·This algorithm repeats recursively until all newly resolved subgroups have no further subgroups.
此算法递归地重复，直到所有新解析的子组不再包含子组。
5·This algorithm repeats recursively until all newly resolved subgroups contain no further subgroups.
此算法递归地重复，直到所有新解析的子组不再包含子组。
