Field Detail

sector

protected Sector sector

Constructor Detail

SurfaceSector

public SurfaceSector()

Constructs a new surface sector with the default attributes and the Sector.EMPTY_SECTOR.

SurfaceSector

public SurfaceSector(Sector sector)

Constructs a new surface sector with the specified sector.

Parameters:

sector - the shape's sector.

Throws:

IllegalArgumentException - if the sector is null.

SurfaceSector

public SurfaceSector(ShapeAttributes normalAttrs)

Constructs a new surface sector with the specified normal (as opposed to highlight) attributes and the Sector.EMPTY_SECTOR. Modifying the attribute reference after calling this constructor causes this shape's appearance to change accordingly.

Parameters:

normalAttrs - the normal attributes. May be null, in which case default attributes are used.

SurfaceSector

public SurfaceSector(ShapeAttributes normalAttrs,
                     Sector sector)

Constructs a new surface sector with the specified normal (as opposed to highlight) attributes and the specified sector. Modifying the attribute reference after calling this constructor causes this shape's appearance to change accordingly.

Parameters:

normalAttrs - the normal attributes. May be null, in which case default attributes are used.

sector - the shape's sector.

Throws:

IllegalArgumentException - if the sector is null.

Method Detail

createGeometry

protected List<List<LatLon>> createGeometry(Globe globe,
                                            SurfaceTileDrawContext sdc)

Specified by:

createGeometry in class AbstractSurfaceShape

doGetRestorableState

protected void doGetRestorableState(RestorableSupport rs,
                                    RestorableSupport.StateObject context)

Overrides:

doGetRestorableState in class AbstractSurfaceShape

doMoveTo

protected void doMoveTo(Position oldReferencePosition,
                        Position newReferencePosition)

Specified by:

doMoveTo in class AbstractSurfaceShape

doRestoreState

protected void doRestoreState(RestorableSupport rs,
                              RestorableSupport.StateObject context)

Overrides:

doRestoreState in class AbstractSurfaceShape

exportAsKML

protected void exportAsKML(Object output)
                    throws IOException,
                           XMLStreamException

Export the sector to KML as a <Placemark> element. The output object will receive the data. This object must be one of: java.io.Writer java.io.OutputStream javax.xml.stream.XMLStreamWriter

Overrides:

exportAsKML in class AbstractSurfaceShape

Parameters:

output - Object to receive the generated KML.

Throws:

XMLStreamException - If an exception occurs while writing the KML

IOException - if an exception occurs while exporting the data.

AbstractSurfaceShape.export(String, Object)

getLocations

public Iterable<? extends LatLon> getLocations(Globe globe)

Description copied from interface: SurfaceShape

Returns the shape's locations as they appear on the specified globe, or null if the shape has no locations.

Specified by:

getLocations in interface SurfaceShape

Parameters:

globe - the globe the shape is related to.

Returns:

the shapes locations on the globe, or null if the shape has no locations.

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.

Specified by:

getReferencePosition in interface Movable

Specified by:

getReferencePosition in class AbstractSurfaceShape

Returns:

the object's reference position, or null if no reference position is available.

getSector

public Sector getSector()

legacyRestoreState

protected void legacyRestoreState(RestorableSupport rs,
                                  RestorableSupport.StateObject context)

Description copied from class: AbstractSurfaceShape

Restores state values from previous versions of the SurfaceShape state XML. These values are stored or named differently than the current implementation. Those values which have not changed are ignored here, and will restored in AbstractSurfaceShape.doRestoreState(gov.nasa.worldwind.util.RestorableSupport, gov.nasa.worldwind.util.RestorableSupport.StateObject).

Overrides:

legacyRestoreState in class AbstractSurfaceShape

Parameters:

rs - RestorableSupport object which contains the state value properties.

context - active context in the RestorableSupport to read state from.

setSector

public void setSector(Sector sector)
