java.lang.Object org.geotools.renderer.array.PointArray org.geotools.renderer.array.JTSArray
A wrapper around an array of JTS Coordinate
s. As of JTS 1.3, LineString
stores
its internal data as an array of type Coordinate[]
. This JTSArray
class wrap directly this LineString
internal array, in order to avoid object creation
and copies.
