Constructor Detail

JTSGeometries

public JTSGeometries()

Construct an initially empty collection using the default coordinate system. Geometries can be added using add(com.vividsolutions.jts.geom.Geometry) method.

JTSGeometries

public JTSGeometries(CoordinateSystem cs)

Construct an initialy empty collection. Geometries can be added using add(com.vividsolutions.jts.geom.Geometry) method.

Parameters:

cs - The coordinate system to use for all points in this geometry, or null if unknow.

JTSGeometries

public JTSGeometries(com.vividsolutions.jts.geom.Geometry geometry)

Construct a collection for the specified geometry. The value is computed from the mean value of all Coordinate.z in the specified geometry.

Parameters:

geometry - The geometry to wrap, or null if none.

Task:

TODO: The coordinate system currently default to PROMISCUOUS. We should find it from the SRID code.

Method Detail

add

public Geometry add(com.vividsolutions.jts.geom.Geometry geometry)
             throws org.opengis.referencing.operation.TransformException,
                    java.lang.IllegalArgumentException

Add the specified geometry to this collection. The geometry must be one of the following classes: Point, LineString, Polygon or GeometryCollection.

Parameters:

geometry - The geometry to add.

Returns:

The geometry as a Geometry wrapper. The style can be set using add(geometry).setStyle(style).

Throws:

org.opengis.referencing.operation.TransformException - if the specified geometry can't be transformed in this collection's coordinate system.

java.lang.IllegalArgumentException - if the geometry is not a a valid class.
