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

Node.getLookup介绍

[英]Obtains a Lookup represeting additional content of this Node. If the lookup was provided in a constructor, it is returned here, if not, a lookup based on the content of getCookie method is provided.
[中]获取表示此节点的其他内容的查找。如果查找是在构造函数中提供的，则在此处返回；如果不是，则提供基于getCookie方法内容的查找。
