Method Detail

• getLines

  public static Collection getLines(Collection geoms,
                                    Collection lines)

  Extracts the linear components from a single Geometry and adds them to the provided Collection.

  Parameters:

  geoms - the collection of geometries from which to extract linear components

  lines - the collection to add the extracted linear components to

  Returns:

  the collection of linear components (LineStrings or LinearRings)

• getLines

  public static Collection getLines(Collection geoms,
                                    Collection lines,
                                    boolean forceToLineString)

  Extracts the linear components from a single Geometry and adds them to the provided Collection.

  Parameters:

  geoms - the Collection of geometries from which to extract linear components

  lines - the collection to add the extracted linear components to

  forceToLineString - true if LinearRings should be converted to LineStrings

  Returns:

  the collection of linear components (LineStrings or LinearRings)

• getLines

  public static Collection getLines(Geometry geom,
                                    Collection lines)

  Extracts the linear components from a single Geometry and adds them to the provided Collection.

  Parameters:

  geom - the geometry from which to extract linear components

  lines - the Collection to add the extracted linear components to

  Returns:

  the Collection of linear components (LineStrings or LinearRings)

• getLines

  public static Collection getLines(Geometry geom,
                                    Collection lines,
                                    boolean forceToLineString)

  Extracts the linear components from a single Geometry and adds them to the provided Collection.

  Parameters:

  geom - the geometry from which to extract linear components

  lines - the Collection to add the extracted linear components to

  forceToLineString - true if LinearRings should be converted to LineStrings

  Returns:

  the Collection of linear components (LineStrings or LinearRings)

• getLines

  public static List getLines(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 LinearComponentExtracter instance and pass it to multiple geometries.

  Parameters:

  geom - the geometry from which to extract linear components

  Returns:

  the list of linear components

• getLines

  public static List getLines(Geometry geom,
                              boolean forceToLineString)

  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 LinearComponentExtracter instance and pass it to multiple geometries.

  Parameters:

  geom - the geometry from which to extract linear components

  forceToLineString - true if LinearRings should be converted to LineStrings

  Returns:

  the list of linear components

• setForceToLineString

  public void setForceToLineString(boolean isForcedToLineString)

  Indicates that LinearRing components should be converted to pure LineStrings.

  Parameters:

  isForcedToLineString - true if LinearRings should be converted to LineStrings

• 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.
