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

Geometry.copy介绍

[英]Creates a deep copy of this Geometry object. Coordinate sequences contained in it are copied. All instance fields are copied (i.e. the SRID and userData).

NOTE: the userData object reference (if present) is copied, but the value itself is not copied. If a deep copy is required this must be performed by the caller.
[中]创建此几何体对象的深度副本。将复制其中包含的坐标序列。复制所有实例字段（即SRID和userData）。
注意：会复制userData对象引用（如果存在），但不会复制值本身。如果需要深度复制，则必须由调用方执行。
