Geometry.setUserData介绍

[英]A simple scheme for applications to add their own custom data to a Geometry. An example use might be to add an object representing a Coordinate Reference System.

Note that user data objects are not present in geometries created by construction methods.
[中]应用程序向几何图形添加自己的自定义数据的简单方案。例如，可以添加表示坐标参照系的对象。
请注意，由构造方法创建的几何图形中不存在用户数据对象。
