extractSegmentStrings

public static List extractSegmentStrings(Geometry geom)

Extracts all linear components from a given Geometry to SegmentStrings. The SegmentString data item is set to be the source Geometry.

Parameters:

geom - the geometry to extract from

Returns:

a List of SegmentStrings

extractNodedSegmentStrings

public static List extractNodedSegmentStrings(Geometry geom)

Extracts all linear components from a given Geometry to SegmentStrings. The SegmentString data item is set to be the source Geometry.

Parameters:

geom - the geometry to extract from

Returns:

a List of SegmentStrings

toGeometry

public static Geometry toGeometry(Collection segStrings,
                                  GeometryFactory geomFact)

Converts a collection of SegmentStrings into a Geometry. The geometry will be either a LineString or a MultiLineString (possibly empty).

Parameters:

segStrings - a collection of SegmentStrings

Returns:

a LineString or MultiLineString

toString

public static String toString(List segStrings)
