                     LatLon northeastCorner,
                     double elevation)

Method Detail

doDrag

protected void doDrag(DragContext dragContext)

drag

public void drag(DragContext dragContext)

Description copied from interface: Draggable

Drag the object given the provided DragContext.

Specified by:

drag in interface Draggable

Parameters:

dragContext - the DragContext of this dragging event.

getAntiAliasHint

public int getAntiAliasHint()

getColor

public java.awt.Color getColor()

getCorners

public LatLon[] getCorners()

getElevation

public double getElevation()

getImageSource

public java.lang.Object getImageSource()

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

Returns:

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

initializeTextureCoordinates

protected void initializeTextureCoordinates()

isDragEnabled

public boolean isDragEnabled()

Description copied from interface: Draggable

Indicates whether the object is enabled for dragging.

Specified by:

isDragEnabled in interface Draggable

Returns:

true if the object is enabled, else false.

move

public void move(Position delta)

Description copied from interface: Movable

Shift the shape over the globe's surface while maintaining its original azimuth, its orientation relative to North.

Specified by:

move in interface Movable

Parameters:

delta - the latitude and longitude to add to the shape's reference position.

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

Parameters:

position - the new position of the shape's reference position.

render

public void render(DrawContext dc)

Description copied from interface: Renderable

Causes this Renderable to render itself using the provided draw context.

Specified by:

render in interface Renderable

Parameters:

dc - the DrawContext to be used

setDragEnabled

public void setDragEnabled(boolean enabled)

Description copied from interface: Draggable

Controls whether the object is enabled for dragging.

Specified by:

setDragEnabled in interface Draggable

Parameters:

enabled - true if the object is enabled, else false.

setElevation

public void setElevation(double elevation)

setImageSource

public void setImageSource(java.lang.Object imageSource)
