Class IsSimpleOp

java.lang.Object
  com.vividsolutions.jts.operation.IsSimpleOp

public class IsSimpleOp
extends java.lang.Object

Tests whether a Geometry is simple. In general, the SFS specification of simplicity follows the rule:

• A Geometry is simple iff the only self-intersections are at boundary points.

Simplicity is defined for each Geometry subclass as follows:

• Valid polygonal geometries are simple by definition, so isSimple trivially returns true.
• 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
