Class EdgeRing

Method Details

• isIsolated

  public boolean isIsolated()

• isHole

  public boolean isHole()

• getCoordinate

  public Coordinate getCoordinate(int i)

• getLinearRing

  public LinearRing getLinearRing()

• getLabel

  public Label getLabel()

• isShell

  public boolean isShell()

• getShell

  public EdgeRing getShell()

• setShell

  public void setShell(EdgeRing shell)

• addHole

  public void addHole(EdgeRing ring)

• toPolygon

  public Polygon toPolygon(GeometryFactory geometryFactory)

• computeRing

  public void computeRing()

  Compute a LinearRing from the point list previously collected. Test if the ring is a hole (i.e. if it is CCW) and set the hole flag accordingly.

• getNext

  public abstract DirectedEdge getNext(DirectedEdge de)

• setEdgeRing

  public abstract void setEdgeRing(DirectedEdge de, EdgeRing er)

• getEdges

  public List getEdges()

  Returns the list of DirectedEdges that make up this EdgeRing

  Returns:

  List of DirectedEdges

• getMaxNodeDegree

  public int getMaxNodeDegree()

• setInResult

  public void setInResult()

• containsPoint

  public boolean containsPoint(Coordinate p)

  This method will cause the ring to be computed. It will also check any holes, if they have been assigned.

  Parameters:

  p - point

  Returns:

  true of ring contains point
