LinearRingDoubleGf

public class LineStringDoubleGf
extends AbstractLineString
implements LineString

Models an OGC-style LineString. A LineString consists of a sequence of two or more vertices, along with all points along the linearly-interpolated curves (line segments) between each pair of consecutive vertices. Consecutive vertices may be equal. The line segments in the line may intersect each other (in other words, the linestring may "curl back" in itself and self-intersect. Linestrings with exactly two identical points are invalid.

A linestring must have either 0 or 2 or more points. If these conditions are not met, the constructors throw an IllegalArgumentException

                  int axisCount,
                  double... points)

Method Detail

getNewCoordinates

public static double[] getNewCoordinates(GeometryFactory geometryFactory,
                         int axisCount,
                         int vertexCount,
                         double... coordinates)

clone

public LineStringDoubleGf clone()

Creates and returns a full copy of this LineString object. (including all coordinates contained by it).

Specified by:

clone in interface Geometry

Specified by:

clone in interface LineString

Overrides:

clone in class AbstractLineString

Returns:

a clone of this instance

convertCoordinates

protected double[] convertCoordinates(GeometryFactory geometryFactory)

Overrides:

convertCoordinates in class AbstractLineString

getBoundingBox

public BoundingBox getBoundingBox()

Description copied from class: AbstractGeometry

Gets an BoundingBoxDoubleGf containing the minimum and maximum x and y values in this Geometry. If the geometry is empty, an empty BoundingBoxDoubleGf is returned.

The returned object is a copy of the one maintained internally, to avoid aliasing issues. For best performance, clients which access this boundingBox frequently should cache the return value.

Specified by:

getBoundingBox in interface Geometry

Overrides:

getBoundingBox in class AbstractGeometry

Returns:

the boundingBox of this Geometry.

getCoordinate

public double getCoordinate(int vertexIndex,
                   int axisIndex)

Specified by:

getCoordinate in interface LineString

getCoordinates

public double[] getCoordinates()

Specified by:

getCoordinates in interface LineString

Specified by:

getCoordinates in class AbstractLineString

getGeometryFactory

public GeometryFactory getGeometryFactory()

Description copied from interface: Geometry

Gets the geometryFactory which contains the context in which this geometry was created.

Specified by:

getGeometryFactory in interface Geometry

Overrides:

getGeometryFactory in class AbstractGeometry

Returns:

the geometryFactory for this geometry

getUserData

public Object getUserData()

Gets the user data object for this geometry, if any.

Specified by:

getUserData in interface Geometry

Overrides:

getUserData in class AbstractGeometry

Returns:

the user data object, or null if none set

getVertexCount

public int getVertexCount()

Description copied from interface: Geometry

Returns the count of this Geometrys vertices. The Geometry s contained by composite Geometrys must be Geometry's; that is, they must implement getNumPoints

Specified by:

getVertexCount in interface Geometry

Returns:

the number of vertices in this Geometry

isEmpty

public boolean isEmpty()

Description copied from class: AbstractGeometry

Tests whether the set of points covered by this Geometry is empty.

Specified by:

isEmpty in interface Geometry

Specified by:

isEmpty in class AbstractGeometry

Returns:

true if this Geometry does not cover any points

setUserData

public void setUserData(Object userData)

A simple scheme for applications to add their own custom data to a Geometry. An example use might be to add an object representing a Point Reference System.

Note that user data objects are not present in geometries created by construction methods.

Specified by:

setUserData in interface Geometry

Overrides:

setUserData in class AbstractGeometry

Parameters:

userData - an object, the semantics for which are defined by the application using this Geometry
