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

Node.getCookie介绍

[英]Get a cookie for this node.

The set of cookies can change. If a node changes its set of cookies, it fires a property change event with #PROP_COOKIE.

If the Node was constructed with a Lookup in constructor than this method delegates to the provided lookup object.
[中]获取此节点的cookie。
这组cookie可以更改。如果节点更改其COOKIE集，它将使用#PROP_COOKIE触发属性更改事件。
如果节点是用Lookupin构造函数构造的，则此方法将委托给提供的查找对象。
