  Returns:

If the position is greater than the list of current points, the point will be added to the end of the poly. This method is convenient because it lets you define the GrabPoint object to use for the node, in case you need a special type of GrabPoint.

  Returns:
    the index for the point in the polygon, starting with 0.

### deletePoint

    public void deletePoint()

  Delete a point off the end of the polyline/polygon.

### deletePoint

    public void deletePoint(int position)

  Delete a point at a certain point in the polygon coordinate list. If the position is less than zero, the deleted point will be the starting point. If the position is greater than the list of current points, the point will be deleted from the end of the poly.

### move

    public void move(java.awt.event.MouseEvent e)

  Called to set the OffsetGrabPoint to the current mouse location, and update the OffsetGrabPoint with all the other GrabPoint locations, so everything can shift smoothly. Should also set the OffsetGrabPoint to the movingPoint. Should be called only once at the beginning of the general movement, in order to set the movingPoint. After that, redraw(e) should just be called, and the movingPoint will make the adjustments to the graphic that are needed.

  Specified by:
    `move` in class `EditableOMGraphic`

### addPolyGrabPointsToOGP

    protected void addPolyGrabPointsToOGP(OffsetGrabPoint ogp)

  This method adds all the GrabPoints associated with the polygon nodes and adds them to the offset GrabPoint representing the lat/lon anchor point.

### generate

    public boolean generate(Projection proj)

  Use the current projection to place the graphics on the screen. Has to be called to at least assure the graphics that they are ready for rendering. Called when the graphic position changes.

  Specified by:

    `render` in class `EditableOMGraphic`
  Parameters:
    `graphics` - java.awt.Graphics.

### setGrabPoints

    public boolean setGrabPoints(GrabPoint[] points)

  Set the grab point objects within the EditableOMGraphic array. For the EditableOMPoly, with its variable number of GrabPoints, this just sets up a new list of all the grab points to look at. It's different than the polyGrabPoints, which are the grab points just on the polygon. This list includes the offset grab point. This method should be called when a new point gets added to the polygon, and should take an array of all the GrabPoints created. It will add the offsetGrabPoint to the end of the array.

  Overrides:
    `setGrabPoints` in class `EditableOMGraphic`
  Parameters:
    `points` - a GrabPoint[] for the points on the polygon.
  Returns:
    true if the grab point array was exactly what the EditableOMGraphic was expecting, in terms of length of the GrabPoint array length. The method copies the array values that fit into the resident array.

### getGrabPoints

    public GrabPoint[] getGrabPoints()

  Get the array of grab points used for the EditableOMGraphic. Creates the array by copying all the grab points out of the ArrayList, and tacking the offset grab point to the end.

  Overrides:
    `getGrabPoints` in class `EditableOMGraphic`

### setGrabPoint

    public boolean setGrabPoint(GrabPoint gb,
                                int index)

  Set the GrabPoint at a particule index of the array. This can be used to tie two different grab points together. This used to work with the gPoints array declared in EditableOMGraphic - no longer. If the index is -1, the offset grab point is set, and any other index refers to the concurrent polygon point.

  Overrides:
    `setGrabPoint` in class `EditableOMGraphic`
  Parameters:
    `gb` - GrabPoint to assign within array.
    `index` - the index of the array to put the GrabPoint. This index should be -1 for the offset grab point, or the index of the corner of the poly, in order starting from 0.
  Returns:
    If the grab point or array is null, or if the index is outside the range of the array, false is returned. If everything goes OK, then true is returned.

### whichGrabPoint

    public int whichGrabPoint(GrabPoint gp)

  Given a grab point, return its index into the polygon array. If its not in the array, the next available index is returned.

### getGrabPoint

    public GrabPoint getGrabPoint(int index)

  Return a particular GrabPoint at a particular point in the array. The EditableOMGraphic should describe which indexes refer to which grab points in the EOMG GrabPoint array. If the index is OFFSET_POINT_INDEX, the offset point is returned. If the index is otherwise outside the range of the array, null is returned.

  Overrides:
    `getGrabPoint` in class `EditableOMGraphic`

### getGUI

    public java.awt.Component getGUI(GraphicAttributes graphicAttributes)

  Adds widgets to modify polygon.

  Overrides:
