Method Detail

doGetRestorableState

protected void doGetRestorableState(RestorableSupport rs,
                                    RestorableSupport.StateObject context)
Overrides:
doGetRestorableState in class ConformingShape

doRestoreState

protected void doRestoreState(RestorableSupport rs,
                              RestorableSupport.StateObject context)
Overrides:
doRestoreState in class ConformingShape

getArea

public double getArea(Globe globe)
Description copied from interface: MeasurableArea
Returns the object's area in square meters. If the object conforms to terrain, the area returned is the surface area of the terrain, including its hillsides and other undulations.

Parameters:
globe - The globe the object is related to.
Returns:
the object's area in square meters. Returns -1 if the object does not form an area due to an insufficient number of vertices or any other condition.

getHeight

public double getHeight(Globe globe)
Description copied from interface: MeasurableArea
Returns the latitudanl length of the object in meters. The length is the distance from the objects south-most point to its east-most position.

Parameters:
globe - The globe the object is related to.
Returns:
the height of the object in meters.

getLength

public double getLength(Globe globe)
Description copied from interface: MeasurableLength
Returns the object's length in meters. If the object conforms to terrain, the length is that along the terrain, including its hillsides and other undulations.

Parameters:
globe - The globe the object is related to.
Returns:
the object's length in meters.

getPerimeter

public double getPerimeter(Globe globe)
Description copied from interface: MeasurableArea
Returns the length of the object's perimeter in meters. If the object conforms to terrain, the perimeter is that along the terrain, including its hillsides and other undulations.

Parameters:
globe - The globe the object is related to.
Returns:
the object's perimeter in meters. Returns -1 if the object does not form an area due to an insufficient number of vertices or any other condition.

getReferencePosition

public Position getReferencePosition()
Specified by:
getReferencePosition in interface Movable
Specified by:
getReferencePosition in class ConformingShape

getWidth

public double getWidth(Globe globe)
Description copied from interface: MeasurableArea
Returns the longitudinal length of the object in meters. The length is the distance from the object's west-most point to its east-most. If the object is terrain conforming then the

Parameters:
globe - The globe the object is related to.
Returns:
the width of the object in meters.

invalidateCache

protected void invalidateCache()
Specified by:
invalidateCache in class ConformingShape

moveTo

public void moveTo(Position position)
Description copied from interface: Movable
Move the shape over the globe's surface while maintaining its original azimuth, its orientation relative to North.

Specified by:
moveTo in interface Movable
Specified by:
moveTo in class ConformingShape
Parameters:
position - the new position of the shape's reference position.

renderBoundary

protected void renderBoundary(DrawContext dc,
                              javax.media.opengl.GL gl,
                              boolean knownToBeVisible)
Specified by:
renderBoundary in class ConformingShape

renderInterior

protected boolean renderInterior(DrawContext dc,
                                 javax.media.opengl.GL gl)
Specified by:
renderInterior in class ConformingShape
