Method Detail

createCoordinateList

public List<Coordinate> createCoordinateList(org.geotoolkit.gml.xml.AbstractGeometry gmlGeometry)

Description copied from interface: CoordinateListFactory

Creates a list of coordinates from a GML geometry representation. The sequence typically includes the constituent vertices.

Specified by:

createCoordinateList in interface CoordinateListFactory

Parameters:

gmlGeometry - A GML geometry object (constructed from its XML representation).

Returns:

A list of 2D coordinates that constitute the geometry.

getCoordinateList

List<Coordinate> getCoordinateList(org.geotoolkit.gml.xml.Curve curve)

Returns a list of points on a curve consisting of one or more segments.

Parameters:

curve - A gml:Curve geometry instance.

Returns:

A list of coordinates on the curve.

getCoordinateList

List<Coordinate> getCoordinateList(org.geotoolkit.gml.xml.LineString lineString)

Returns a list of points representing the vertices of a LineString geometry.

Parameters:

lineString - A gml:LineString geometry instance.

Returns:

The list of vertices.

getCoordinateList

List<Coordinate> getCoordinateList(org.geotoolkit.gml.xml.v321.CompositeCurveType compCurve)

Returns a list of points on a composite curve consisting of one or more curve members.

Parameters:

compCurve - A gml:CompositeCurve geometry instance.

Returns:

A list of points on the entire curve; the interpolation method may vary along its length.

getCoordinateList

List<Coordinate> getCoordinateList(org.geotoolkit.gml.xml.v321.OrientableCurveType orientableCurve)

Returns a list of points on an orientable curve. If the orientation is positive ("+"), then the orientable curve is identical to the base curve; otherwise the base curve is traversed in reverse order.

Parameters:

orientableCurve - A gml:OrientableCurve geometry instance.

Returns:

A list of points on the (base) curve; the order reflects the orientation with respect to the base curve.

getCoordinateList

List<Coordinate> getCoordinateList(org.geotoolkit.gml.xml.v321.AbstractRingType ring)
                             throws Exception

Returns a list of points on a ring representing a single connected component of a surface boundary. A ring is structurally similar to a composite curve.

Parameters:

ring - A ring (gml:Ring or gml:LinearRing element).

Returns:

A list of points on a ring (closed curve).

Throws:

Exception - If a curve member could not be accessed or parsed.
