Constructor Detail

CurveReference

public CurveReference(GMLReferenceResolver resolver,
                      String uri,
                      String baseURL)

Creates a new CurveReference instance.

Parameters:

resolver - used for resolving the reference, must not be null

uri - the geometry's uri, must not be null

baseURL - base URL for resolving the uri, may be null (no resolving of relative URLs)

Method Detail

getAsLineString

public LineString getAsLineString()

Description copied from interface: Curve

Returns a linear interpolated representation of the curve.

NOTE: This method is only safe to use when the curve is a LineString or LinearRing or it only consists of LineStringSegments. In any other case it will fail.

Specified by:

getAsLineString in interface Curve

Returns:

curve as a linestring

getBoundary

public Pair<Point,Point> getBoundary()

Description copied from interface: Curve

The boundary of a curve is the set of points at either end of the curve. If the curve is a cycle, the two ends are identical, and the curve (if topologically closed) is considered to not have a boundary.

Specified by:

getBoundary in interface Curve

Returns:

boundary of a curve. If a curve does not have a boundary because it is closed an empty List shall be retruned

getControlPoints

public Points getControlPoints()

Description copied from interface: Curve

Convenience method for accessing the control points of linear interpolated curves.

NOTE: This method is only safe to use when the curve is a LineString or LinearRing or it only consists of LineStringSegments. In any other case it will fail.

Specified by:

getControlPoints in interface Curve

Returns:

the control points

getCurveSegments

public List<CurveSegment> getCurveSegments()

Description copied from interface: Curve

Returns the segments that constitute this curve.

Specified by:

getCurveSegments in interface Curve

Returns:

the segments that constitute this curve

getCurveType

public Curve.CurveType getCurveType()

Description copied from interface: Curve

Returns the type of curve.

Specified by:

getCurveType in interface Curve

Returns:

the type of curve

getEndPoint

public Point getEndPoint()

Description copied from interface: Curve

Returns the end point of the curve.

Specified by:

getEndPoint in interface Curve

Returns:

the end point of the curve

getLength

public Measure getLength(Unit requestedUnit)

Specified by:

getLength in interface Curve

Returns:

length of the curve

getPrimitiveType

public GeometricPrimitive.PrimitiveType getPrimitiveType()

Description copied from interface: GeometricPrimitive

Returns the type of primitive.

Specified by:

getPrimitiveType in interface Curve

Specified by:

getPrimitiveType in interface GeometricPrimitive

Overrides:

getPrimitiveType in class GeometricPrimitiveReference<T extends Curve>

Returns:

the type of primitive

getStartPoint

public Point getStartPoint()

Description copied from interface: Curve

Returns the start point of the curve.

Specified by:

getStartPoint in interface Curve

Returns:

the start point of the curve

isClosed

public boolean isClosed()

Description copied from interface: Curve

Returns whether the curve forms a closed loop.

Specified by:

isClosed in interface Curve

Returns:

true, if the curve forms a closed loop, false otherwise
