Examples of GeometryLocation

com.vividsolutions.jts.operation.distance.GeometryLocation
Represents the location of a point on a Geometry. Maintains both the actual point location (which may not be exact, if the point is not a vertex) as well as information about the component and segment index where the point occurs. Locations inside area Geometrys will not have an associated segment index, so in this case the segment index will have the sentinel value of {@link #INSIDE_AREA}. @version 1.7
