org.geotools.geometry.iso.operation.IsSimpleOp
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 {@link 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
