包路径：org.locationtech.jts.geom.Geometry
类名称：Geometry
方法名：difference

Geometry.difference介绍

[英]Computes a Geometry representing the closure of the point-set of the points contained in this Geometry that are not contained in the other Geometry.

If the result is empty, it is an atomic geometry with the dimension of the left-hand input.

Non-empty GeometryCollection arguments are not supported.
[中]计算一个Geometry，表示此Geometry中包含的点集的闭合，该点集不包含在other几何图形中。
如果结果为空，则它是具有左手输入尺寸的原子几何体。
不支持非空GeometryCollection参数。
