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

FileUtil.getOrder介绍

[英]Sorts some sibling file objects.

Normally this is done by looking for numeric file attributes named position on the children; children with a lower position number are placed first. Now-deprecated relative ordering attributes of the form earlier/later may also be used; if the above attribute has a boolean value of true, then the file named earlier will be sorted somewhere (not necessarily directly) before the file named later. Numeric and relative attributes may also be mixed.

The sort is stable at least to the extent that if there is no ordering information whatsoever, the returned list will be in the same order as the incoming collection.
[中]对某些同级文件对象进行排序。
通常，这是通过在子对象上查找名为position的数字文件属性来完成的；位置号较低的儿童排在第一位。现在也可以使用earlier/later形式的不推荐的相对排序属性；如果上述属性的布尔值为true，则名为earlier的文件将排序在名为later的文件之前的某个位置（不一定直接排序）。数字属性和相对属性也可以混合使用。
排序是稳定的，至少在某种程度上，如果没有任何排序信息，返回的列表将与传入集合的顺序相同。
