All Implemented Interfaces:

Edge, RepastGisFeature

Direct Known Subclasses:

DrawableLineString

public class LineStringAdapter

extends DefaultEdge

implements RepastGisFeature

This is an adapter between a geotools LineString, a JTS LineString and a Repast Edge. It contains all of the good bits from each of those.

Constructor Detail

LineStringAdapter

public LineStringAdapter(SpatialNode from,
                         SpatialNode to)

Create a lineString from two spatial nodes. In reality most times one will be creating these from a datasource, but if ever the need should arise, this will work also.

Parameters:

from -

to -

LineStringAdapter

public LineStringAdapter(org.geotools.feature.Feature f)
                  throws Exception

Create a LineString adapter from a Geotools feature. This will be the most common way of creating a LineStringAdapter

Parameters:

f -

Throws:

Exception

LineStringAdapter

public LineStringAdapter(com.vividsolutions.jts.geom.Geometry geo,
                         Hashtable attr)
                  throws Exception

Create a lineStringAdapter from a geometry (linestring) and an attributes table.

Parameters:

geo -

attr -

Method Detail

getLength

public double getLength()

Calculates the distance of the linestring.

Returns:

setGeometry

public void setGeometry(com.vividsolutions.jts.geom.Geometry geo)
                 throws IllegalArgumentException

set the geometry for this feature.

Specified by:

setGeometry in interface RepastGisFeature

Parameters:

geo -

IllegalArgumentException

setFeature

public void setFeature(org.geotools.feature.Feature f)
                throws Exception

Description copied from interface: RepastGisFeature

Set the gis feature. This feature includes both the geometry data and the attributes.

Specified by:

setFeature in interface RepastGisFeature

Parameters:

f - The feature to be added

Throws:

Exception - throws an exception if this is not a proper feature.
