getReferencePosition
public Position getReferencePosition()
Description copied from interface:Movable
A position associated with the object that indicates its aggregate geographic position. The chosen position varies among implementers of this interface. For objects defined by a list of positions, the reference position is typically the first position in the list. For symmetric objects the reference position is often the center of the object. In many cases the object's reference position may be explicitly specified by the application.- Returns:
- the object's reference position, or null if no reference position is available.

createSurfaceShape
protected SurfaceShape createSurfaceShape()
Description copied from class:AbstractAirspace
Returns aSurfaceShape
that corresponds to this Airspace and is used for drawing on 2D globes.- Overrides:

- Returns:
- The surface shape to represent this Airspace on a 2D globe.
-
updateSurfaceShape
protected void updateSurfaceShape(DrawContext dc, SurfaceShape shape)
Description copied from class:AbstractAirspace
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.- Overrides:
updateSurfaceShape
in classAbstractAirspace
- Parameters:
dc
- the current drawing context.shape
- the surface shape to update.
-
regenerateSurfaceShape
protected void regenerateSurfaceShape(DrawContext dc, SurfaceShape shape)

in classAbstractAirspace
- Parameters:
dc
- the current drawing context.shape
- the surface shape to regenerate.
