public abstract class PointExpression<T extends org.geolatte.geom.Point>
extends GeometryExpression<T>

A Point is a 0-dimensional geometric object and represents a single location in coordinate space. A Point has an x-coordinate value, a y-coordinate value. If called for by the associated Spatial Reference System, it may also have coordinate values for z and m.
