Constructor Detail

ComponentCoordinateExtracter

public ComponentCoordinateExtracter(List coords)

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

Method Detail

getCoordinates

public static List getCoordinates(Geometry geom)

Extracts a representative Coordinate from each connected component in a geometry.

If more than one geometry is to be processed, it is more efficient to create a single ComponentCoordinateExtracter instance and pass it to each geometry.

Parameters:

geom - the Geometry from which to extract

Returns:

a list of representative Coordinates

filter

public void filter(Geometry geom)

Description copied from interface: GeometryComponentFilter

Performs an operation with or on a geometry component.

Specified by:

filter in interface GeometryComponentFilter

Parameters:

geom - a component of the geometry to which the filter is applied.
