Method Detail

createAddCommand

public UndoableCommand createAddCommand(org.locationtech.jts.geom.Geometry geometry,
                                        boolean rollingBackInvalidEdits,
                                        LayerViewPanel layerViewPanel,
                                        AbstractCursorTool tool)

The calling CursorTool should call #preserveUndoHistory; otherwise the undo history will be (unnecessarily) truncated if a problem occurs.

Returns:

null if the geometry is invalid

prepare

public CursorTool prepare(AbstractCursorTool drawFeatureTool,
                          boolean allowSnapping)

Apply settings common to all feature-drawing tools.createAddCommand

drawRing

public void drawRing(org.locationtech.jts.geom.Polygon polygon,
                     boolean rollingBackInvalidEdits,
                     AbstractCursorTool tool,
                     LayerViewPanel panel)

reverse

public org.locationtech.jts.geom.LineString reverse(org.locationtech.jts.geom.LineString lineString)

Parameters:

lineString - to reverse

Returns:

new LineString made from old LineString's points in reverse order

concatLineStrings

public org.locationtech.jts.geom.LineString concatLineStrings(org.locationtech.jts.geom.LineString ls1,
                                                              org.locationtech.jts.geom.LineString ls2)

Parameters:

ls1 - first LineString to concatenate

ls2 - second LineString to concatenate

Returns:

new LineString made of (first - last point) + second

mergeLineStrings

public org.locationtech.jts.geom.LineString mergeLineStrings(org.locationtech.jts.geom.LineString ls1,
                                                             org.locationtech.jts.geom.LineString ls2)

Parameters:

ls1 - first LineString to merge

ls2 - second LineString to merge

Returns:

merged LineString if end point in common, otherwise return second LineString

drawLineString

public void drawLineString(org.locationtech.jts.geom.LineString newLineString,
                           boolean rollingBackInvalidEdits,
                           AbstractCursorTool tool,
                           LayerViewPanel panel)

Implement the special check for adding to the end of a selected LineString

Parameters:

newLineString - LineString to create or add to selected

rollingBackInvalidEdits - true to rollback invalid edits

tool - AbstractCursorTool - the current cursor tool

panel - LayerViewPanel

selectGeometry

public void selectGeometry(LayerViewPanel panel,
                           org.locationtech.jts.geom.Geometry geom)
