  public ComponentCoordinateExtracter(List coords)
  
  Constructs a LineExtracterFilter with a list in which to store LineStrings found.
Method Details
- getCoordinates
  
  public static 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 ComponentCoordinateExtracter 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.
