Geometry.isSimple介绍

[英]Tests whether this Geometry is simple. The SFS definition of simplicity follows the general rule that a Geometry is simple if it has no points of self-tangency, self-intersection or other anomalous points.

Simplicity is defined for each Geometry subclass as follows:

• Valid polygonal geometries are simple, since their rings must not self-intersect. isSimple tests for this condition and reports false if it is not met. (This is a looser test than checking for validity).
• Linear rings have the same semantics.
• Linear geometries are simple iff they do not self-intersect at points other than boundary points.
• Zero-dimensional geometries (points) are simple iff they have no repeated points.
• Empty Geometrys are always simple.
  [中]测试此几何图形是否简单。SFS简单性定义遵循的一般规则是，如果几何体没有自切点、自相交点或其他异常点，则几何体是简单的。
  每个几何体子类的简单性定义如下：
  *有效的多边形几何体很简单，因为它们的环不能自相交。isSimple测试此条件，如果不满足，则报告false。（这是一个比检查有效性更宽松的测试）。
  *线性环具有相同的语义。
  *线性几何体很简单，除非它们在边界点以外的点上不自相交。
  *零维几何（点）是简单的，如果它们没有重复的点。
  *空的Geometry总是很简单的。
