Method Detail

getCoordinateDimension

public int getCoordinateDimension()

Description copied from interface: Geometry

Returns the coordinate dimension, i.e. the dimension of the space that the geometry is embedded in.

Specified by:

getCoordinateDimension in interface Geometry

Overrides:

getCoordinateDimension in class DefaultRing

Returns:

the coordinate dimension

getCurveType

public Curve.CurveType getCurveType()

Description copied from interface: Ring

Must always return Curve.CurveType.Ring.

Specified by:

getCurveType in interface Curve

Specified by:

getCurveType in interface Ring

Overrides:

getCurveType in class DefaultRing

Returns:

Curve.CurveType.Ring

getRingType

public Ring.RingType getRingType()

Description copied from interface: Ring

Returns the type of ring.

Specified by:

getRingType in interface LinearRing

Specified by:

getRingType in interface Ring

Overrides:

getRingType in class DefaultRing

Returns:

the type of ring

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

Overrides:

getAsLineString in class DefaultRing

Returns:

curve as a linestring

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

Overrides:

getControlPoints in class DefaultRing

Returns:

the control points

buildJTSGeometry

protected com.vividsolutions.jts.geom.LinearRing buildJTSGeometry()

Overrides:

buildJTSGeometry in class DefaultRing
