ComponentCoordinateExtracter

public ComponentCoordinateExtracter(java.util.List coords)

Constructs a LineExtracterFilter with a list in which to store LineStrings found.

Method Detail

getCoordinates

public static java.util.List getCoordinates(Geometry geom)

Extracts the linear components from a single geometry. If more than one geometry is to be processed, it is more efficient to create a single LineExtracterFilter instance and pass it to multiple geometries.

Parameters:

geom - the Geometry from which to extract

Returns:

a list of Coordinates

filter

public void filter(Geometry geom)

Description copied from interface: GeometryComponentFilter

Performs an operation with or on geom.

Specified by:

filter in interface GeometryComponentFilter

Parameters:

geom - a Geometry to which the filter is applied.
