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

Children.snapshot介绍

[英]Creates an immutable snapshot representing the current view of the nodes in this children object. This is No attempt is made to extract incorrect or invalid nodes from the list, as a result, the value may not be exactly the same as returned by #getNodes().
[中]创建表示此子对象中节点的当前视图的不可变快照。这不是试图从列表中提取不正确或无效的节点，因此，该值可能与#getNodes（）返回的值不完全相同。
