LineStringImpl
public LineStringImpl(java.util.List<org.opengis.geometry.coordinate.Position> positions)
LineStringImpl
public LineStringImpl(LineStringImpl lineString)
- Constructor by another LineString The constructor for LineString takes a sequence of points
and constructs a LineString with those points as controlPoints. The constructor of a
LineString takes two or more positions and creates the appropriate line string joining them.
LineString::LineString(points[2..n]:Position):LineString
- Parameters:
lineString
-
LineStringImpl
public LineStringImpl(PointArrayImpl pointArray,
double startPar)
- Constructor by a PointArray and a StartParam
- Parameters:
pointArray
- startPar
-
merge
public LineStringImpl merge(LineStringImpl other)
- Merges this LineString with another LineString, forming a new LineString The input
LineStrings will not be modified by this operation. The used Lists of the pointArray will be
cloned. The Positions which represents the control points will not be cloned.
- Parameters:
other
- LineString
