Constructor Detail

KMLSurfacePolygonImpl

public KMLSurfacePolygonImpl(KMLTraversalContext tc,
                             KMLGroundOverlay overlay)

Create a surface polygon from a KML GroundOverlay.

Parameters:

tc - the current KMLTraversalContext.

overlay - the KMLGroundOverlay to render as a polygon.

Throws:

NullPointerException - if the geometry is null.

IllegalArgumentException - if the parent placemark or the traversal context is null.

KMLSurfacePolygonImpl

public KMLSurfacePolygonImpl(KMLTraversalContext tc,
                             KMLPlacemark placemark,
                             KMLAbstractGeometry geom)

Create an instance.

Parameters:

tc - the current KMLTraversalContext.

placemark - the Placemark element containing the LineString.

geom - the KMLPolygon geometry.

Throws:

NullPointerException - if the geometry is null.

IllegalArgumentException - if the parent placemark or the traversal context is null.

Method Detail

applyRotation

protected void applyRotation(DrawContext dc)

Apply a rotation to the corner points of the overlay. This method is called the first time the polygon is rendered, if the position is specified using a rotated LatLon box.

Parameters:

dc - Current draw context.

createPickedObject

protected PickedObject createPickedObject(DrawContext dc,
                                          Color pickColor)

Create a PickedObject for this surface object. The PickedObject created by this method will be added to the pick list to represent the current surface object.

Overrides:

createPickedObject in class AbstractSurfaceObject

Parameters:

dc - Active draw context.

pickColor - Unique color for this PickedObject.

Returns:

A new picked object.

getInitialAttributes

protected ShapeAttributes getInitialAttributes(String attrType)

makeAttributesCurrent

protected ShapeAttributes makeAttributesCurrent(String attrType)

Determine and set the Path highlight attributes from the KML Feature fields.

Parameters:

attrType - the type of attributes, either KMLConstants.NORMAL or KMLConstants.HIGHLIGHT.

Returns:

the new attributes.

onMessage

public void onMessage(Message message)

Description copied from class: WWObjectImpl

Empty implementation of MessageListener.

Specified by:

onMessage in interface MessageListener

Overrides:

onMessage in class WWObjectImpl

Parameters:

message - The message that was received.

preRender

public void preRender(KMLTraversalContext tc,
                      DrawContext dc)

Description copied from interface: KMLRenderable

Pre-render this element.

Specified by:

preRender in interface KMLRenderable

Parameters:

tc - the current KML traversal context.

dc - the current draw context.

render

public void render(KMLTraversalContext tc,
                   DrawContext dc)
