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。
