  - setAltitude
```
public void setAltitude(double altitude)
```
    Description copied from interface: Airspace

See Airspace.setAltitudeDatum(String, String) for a description of the possible interpretations and the means to specify them.
    
    Specified by:

    Parameters:
    
    altitude - the lower surface altitude, in meters.

```
public void setAltitudeDatum(java.lang.String lowerAltitudeDatum,
                             java.lang.String upperAltitudeDatum)
```
    Description copied from interface: Airspace
    
    Sets the altitude datum, which indicates whether airspace altitudes are relative to mean sea level, ground level or a single ground reference location.
    A value of AVKey.ABOVE_MEAN_SEA_LEVEL, the default for both lower and upper datums, indicates a datum of mean sea level. The respective lower or upper surface of the airspace is drawn at the constant altitude specified by Airspace.setAltitude(double).
    A datum of AVKey.ABOVE_GROUND_LEVEL indicates that each position of the respective airspace surface is offset vertically from the altitude specified to Airspace.setAltitude(double) by an amount equal to the terrain elevation at that position. For example, if the specified lower altitude is zero, the lower surface lies on and conforms to the terrain. If non-zero, the surface undulates in tandem with the terrain but relative to the specified altitude.
    A datum of AVKey.ABOVE_GROUND_REFERENCE combines both of the above datums. It indicates that the respective surface is drawn at the altitude specified to Airspace.setAltitude(double) but offset vertically by an amount equal to the elevation at a single reference location on the ground. This is useful for displaying surfaces that are "flat" but are positioned relative to the ground. An example is the roof of a building, which maintains a constant altitude even as the base of its building may conform to varying terrain. One method of representing buildings is to specify a lower altitude of 0, a lower altitude datum of AVKey.ABOVE_GROUND_LEVEL, an upper altitude that's the building's height, and an upper altitude datum of AVKey.ABOVE_GROUND_REFERENCE, where the ground reference is a location at the building's base. The reference position is specifed by Airspace.setGroundReference(LatLon).
    
    Specified by:
    
    setAltitudeDatum in interface Airspace
    
    Parameters:
    
    lowerAltitudeDatum - the lower altitude datum.

    Sets the altitude datum for both the lower and upper airspace surface to the same specified value. The datum is normally set via Airspace.setAltitudeDatum(String, String), but this method is provided for backwards compatibility with the means of originally setting the datum. See the argument descriptions for the mapping of the boolean values of this method to the altitude-datum values.
    
    Specified by:
    
    setTerrainConforming in interface Airspace
    
    Parameters:
    
    terrainConformant - the altitude datum. See Airspace.setTerrainConforming(boolean, boolean) for a description of the possible values.
  - setTerrainConforming
```
public void setTerrainConforming(boolean lowerTerrainConformant,
                                 boolean upperTerrainConformant)
```
    Description copied from interface: Airspace
    
    Sets the altitude datum, which indicates whether airspace altitudes are relative to mean sea level, ground level or a single ground reference location. The datum is normally set via Airspace.setAltitudeDatum(String, String), but this method is provided for backwards compatibility with the means of originally setting the datum. See the argument descriptions below for the mapping of the boolean values of this method to the altitude-datum values.
    
    Specified by:
    
    setTerrainConforming in interface Airspace
    
    Parameters:
    
    lowerTerrainConformant - the lower altitude datum. A value of true indicates a lower altitude datum of AVKey.ABOVE_GROUND_LEVEL (terrain conforming), a value of false indicates a lower altitude datum of {link AVKey#ABOVE_MEAN_SEA_LEVEL} (not terrain conforming). the terrain-conforming, a value of false indicates that it's not.
    
    upperTerrainConformant - the upper altitude datum. A value of true indicates an upper altitude datum of AVKey.ABOVE_GROUND_LEVEL (terrain conforming), a value of false indicates an upper altitude datum of {link AVKey#ABOVE_MEAN_SEA_LEVEL} (not terrain conforming. the terrain-conforming, a value of false indicates that it's not.

  - updateExpiryCriteria
```
protected void updateExpiryCriteria(DrawContext dc,
                                    Geometry geom)
```
  - updateSurfaceShape
```
protected void updateSurfaceShape(DrawContext dc,
                                  SurfaceShape shape)
```
    Sets surface shape parameters prior to picking and rendering the 2D shape used to represent this Airspace on 2D globes. Subclasses should override this method if they need to update more than the attributes and the delegate owner.
    
    Parameters:
    
    dc - the current drawing context.
    
    shape - the surface shape to update.
