public abstract class JTSPolygonExpression<T extends com.vividsolutions.jts.geom.Polygon>
extends JTSSurfaceExpression<T>

A Polygon is a planar Surface defined by 1 exterior boundary and 0 or more interior boundaries. Each interior boundary defines a hole in the Polygon. A Triangle is a polygon with 3 distinct, non-collinear vertices and no interior boundary.
