包路径：org.locationtech.jts.geom.GeometryFactory
类名称：GeometryFactory

GeometryFactory介绍

[英]Supplies a set of utility methods for building Geometry objects from lists of Coordinates.

Note that the factory constructor methods do not change the input coordinates in any way. In particular, they are not rounded to the supplied PrecisionModel. It is assumed that input Coordinates meet the given precision.
[中]提供一组实用方法，用于从坐标列表中构建几何体对象。
请注意，工厂构造函数方法不会以任何方式更改输入坐标。特别是，它们没有四舍五入到提供的PrecisionModel。假设输入坐标满足给定精度。
