ShapeEditor (NASA World Wind)

java.lang.Object
- gov.nasa.worldwind.util.ShapeEditor

All Implemented Interfaces:

SelectListener, PropertyChangeListener, EventListener

Direct Known Subclasses:

ShapeEditingExtension.ShapeEditorExtension
```
public class ShapeEditor
extends Object
implements SelectListener, PropertyChangeListener
```
Provides a user interface for editing a shape and performs editing. Depending on the shape type, the shape is shown with control points for vertex locations and size. All shapes are shown with a handle that provides rotation.
Left-drag on the shape's body moves the whole shape. Left-drag on a control point performs the action associated with that control point. The editor provides vertex insertion and removal for airspace Polygon, Curtain, Route and Track shapes, and SurfacePolygon and SurfacePolyline. Shift-left-click when the cursor is over the shape inserts a control point at the cursor's position. Alt-left-click when the cursor is over a control point removes that control point. Control points are added to the ends of airspace Polygon, Curtain, Route and Track, and SurfacePolyline by shift-left-click on the first or last control point of the shape.
This editor supports airspaces other than Cake and all surface shapes except SurfaceMultiPolygon and SurfaceImage.

    Constructs an editor for a specified shape. Once constructed, the editor must be armed to operate. See setArmed(boolean).
    
    Parameters:
    
    wwd - the WorldWindow associated with the specified shape.
    
    originalShape - the shape to edit.
    
    Throws:

- Method Detail
  - addNearestLocation
```
protected int addNearestLocation(Position terrainPosition,
                                 double altitude,
                                 List<LatLon> locations)
```
    Inserts the location nearest to a specified position on an edge of a specified list of locations into the appropriate place in that list.
    
    Parameters:
    
    terrainPosition - the position to find a nearest point for.
    
    altitude - the altitude to use when determining the nearest point. Can be approximate and is not necessarily the altitude of the terrain position.
    
    locations - the list of locations. This list is modified by this method to contain the new location on an edge nearest the specified terrain position.
    
    Returns:
    
    the index at which the new location was inserted into the list.
  - adjustShape
```
protected void adjustShape()
```
    Performs shape-specific minor modifications to shapes after editing operation are performed. Some editing operations cause positions that are originally identical to become slightly different and thereby disrupt the original connectivity of the shape. This is the case for track-airspace legs, for instance. This method is called just after editing operations are performed in order to give the editor a chance to reform connectivity or otherwise modify the shape to retain its original properties. Subclasses should override this method if they are aware of shapes other than those recognized by default and those shapes need such adjustment during editing.
  - adjustTrackShape
```
protected void adjustTrackShape()
```
    Restores adjacency of TrackAirspace shapes. Called by adjustShape().

```
    Adds a location to either the beginning or the end of a specified list of locations. Which end to add to is determined by a specified control point.
    
    Parameters:
    
    controlPoint - the control point of the shape's end. If the control point's ID is 0 the new location is inserted to the beginning of the list. If the control point ID corresponds to the last location in the list then the new location is appended to the list. Otherwise no operation occurs.
    
    locations - the shape's locations. This list is modified upon return to include the new location.
  - computeControlPointDelta
```
protected Vec4 computeControlPointDelta(LatLon previousLocation,

    length - the distance of the edge from the shape's center.
    
    Returns:
    
    a location at the shape's edge at the same location along the shape's axis as the specified center location.
  - computeRectangularEdgeLocation
```
protected Position computeRectangularEdgeLocation(LatLon begin,
                                                  LatLon end,
                                                  double width)
```
    Computes a control point location at the edge of a rectangular shape.
    
    Parameters:
