包路径：org.openide.nodes.NodeTransfer
类名称：NodeTransfer

NodeTransfer介绍

[英]Class that contains specific datatransfer flavors and methods to work with nodes. There are flavors to allow a node to be copied or cut, and to decide its paste types.

This is a dummy utility class--no instances are possible.
[中]类，该类包含用于处理节点的特定数据传输风格和方法。有一些风格允许复制或剪切节点，并决定其粘贴类型。
这是一个虚拟实用程序类——不可能有任何实例。
