public abstract class AbstractSurfaceShape
extends AbstractSurfaceObject
implements SurfaceShape, Movable, Movable2, Combinable, Draggable
```
Common superclass for surface conforming shapes such as SurfacePolygon, SurfacePolyline, SurfaceEllipse, SurfaceQuad, and SurfaceSector.
SurfaceShapes have separate attributes for normal display and highlighted display. If no attributes are specified, default attributes are used. See DEFAULT_INTERIOR_MATERIAL, DEFAULT_OUTLINE_MATERIAL, and DEFAULT_HIGHLIGHT_MATERIAL.
AbstractSurfaceShape extends from AbstractSurfaceObject, and therefore inherits AbstractSurfaceObject's batch rendering capabilities.

  - canContainPole
```
protected boolean canContainPole()
```
    Indicates whether the shape is a closed polygon that can enclose a pole, or an open path that cannot. This makes a difference when computing the bounding sector for a shape. For example, consider the positions (-100, 85), (0, 80), (100, 80). If these positions are treated as a closed polygon (a triangle over the North Pole) then the bounding sector is 80 to 90 lat, -180 to 180 lon. But if they are treated as an open path (a line wrapping partway around the pole) then the bounding sector is 80 to 85 lat, -100 to 100 lon.
    
    Returns:
    
    True if the shape is a closed polygon that can contain a pole, or false if it is treated as an open path that cannot contain a pole.
  - clearCaches
```
protected void clearCaches()
```
    Clears this SurfaceObject's internal extent cache.
    Overridden to clear this SurfaceShape's internal sector and geometry caches.
    
    Overrides:
    
    clearCaches in class AbstractSurfaceObject
  - combine
```
public void combine(CombineContext cc)
```
    Causes this Combinable to draw its contours using the GLU tessellator attached to the provided CombineContext. When the CombineContext is in bounding sector mode, this adds the Combinable's geographic bounding sector to the CombineContext's bounding sector list. See the interface documentation for more information.
    
    Specified by:
    
    combine in interface Combinable
    
    Parameters:
    
    cc - the CombineContext to be used.

    Returns:
    
    Bounding sectors for the shape.

    Computes the bounding sectors for the shape. There will be more than one if the shape crosses the date line, but does not enclose a pole.
    
    Parameters:
    
    globe - Current globe.
    
    Returns:
    
    Bounding sectors for the shape.
  - containsPole
```
protected String containsPole(Iterable<? extends LatLon> locations)
```
    Determine if a list of geographic locations encloses either the North or South pole. The list is treated as a closed loop. (If the first and last positions are not equal the loop will be closed for purposes of this computation.)
    
    Parameters:
    
    locations - Locations to test.
    
    Returns:
    
    AVKey.NORTH if the North Pole is enclosed, AVKey.SOUTH if the South Pole is enclosed, or null if neither pole is enclosed. Always returns null if canContainPole() returns false.

                                        Globe globe)
```
    Divide a list of locations that encloses a pole along the international date line. This method determines where the locations cross the date line, and inserts locations to the pole, and then back to the intersection position. This allows the shape to be "unrolled" when projected in a lat-lon projection.
    
    Parameters:
    
    locations - Locations to cut at date line. This list is not modified.
    
    pole - Pole contained by locations, either AVKey.NORTH or AVKey.SOUTH.
    
    globe - Current globe.
    
    Returns:
    
    New location list with locations added to correctly handle date line intersection.
