Constructor Detail

• Selection

  public Selection(MapWindow window)

  Create a new Selection for the given window.

  Parameters:

  window - the window to use for the selection. The window is necessary to transform between pixel and geographic values

Method Detail

• add

  public void add(int x,
                  int y)

  Add the point (x, y) to the current line. If the last line is closed or there is no current line, start a new one.

  Parameters:

  x - the x coordinate of the new point.

  y - the y coordinate of the new point.

• remove

  public void remove()

  Remove the last point from the current line. If the current line is empty, the next removal will proceed at a random instance of the other lines.

• close

  public void close()

  If possible (enough points), close the current line to a polygon.

• getGeometries

  public GeometryCollection getGeometries()

  Retrieve the geometries represented by this selection.

  Returns:

  the selection in form of a GeometryCollection

• getGeometriesAsList

  public List<Geometry> getGeometriesAsList()

  Retrieve the geometries represented by this selection.

  Returns:

  the selection in form of a list of geometries.

• getGeometriesAsListDegrees

  public List<Geometry> getGeometriesAsListDegrees()

  Retrieve the geometries represented by this selection.

  Returns:

  the selection in form of a list of geometries.

• fromDegrees

  public void fromDegrees()

  Rebuild the pixel representations of the lines from the degree instances.

• fromPixels

  public void fromPixels()

  Rebuild the geographic representations of the lines from the pixel instances.

• addSelectionChangeListener

  public void addSelectionChangeListener(SelectionChangeListener listener)

  Add a listener that get informed on changes of the selections.

  Parameters:

  listener - the listener to add.

• removeSelectionChangeListener

  public void removeSelectionChangeListener(SelectionChangeListener listener)

  Remove a listener from the list of selection listeners.

  Parameters:

  listener - the listener to remove.

• add

  public void add(LineString string)

  Add the denoted LineString to the list of edited geometries.

  Parameters:

  string - the LineString to add.

• remove

  public void remove(int index)

  Remove the element at the denoted index position from the list of geometries.

  Parameters:

  index - the index of the geometry to remove.

• setEditedGeometry

  public void setEditedGeometry(int index)

  Set the currently edited geometry to the one referenced by the denoted index.

  Parameters:

  index - the index of the geometry to edit.
