类名称：GeometryFactory
方法名：createGeometry

GeometryFactory.createGeometry介绍

[英]Creates a deep copy of the input Geometry. The CoordinateSequenceFactory defined for this factory is used to copy the CoordinateSequences of the input geometry.

This is a convenient way to change the CoordinateSequence used to represent a geometry, or to change the factory used for a geometry.

Geometry#copy() can also be used to make a deep copy, but it does not allow changing the CoordinateSequence type.
[中]创建输入几何图形的深度副本。为此工厂定义的CoordinateSequenceFactory用于复制输入几何图形的CoordinateSequence。
这是更改用于表示几何图形的坐标序列或更改用于几何图形的工厂的方便方法。
Geometry#copy（）也可用于制作深度复制，但它不允许更改CoordinateSequence类型。
