attributes - the attributes to assign to the shape.

getAttributes

public ShapeAttributes getAttributes()

Description copied from interface: Attributable

Return the shape's current attributes.

Specified by:

getAttributes in interface Attributable

Returns:

the shape's current attributes.

setHighlightAttributes

public void setHighlightAttributes(ShapeAttributes attributes)

Description copied from interface: Attributable

Set the shape's highlight attributes.

Specified by:

setHighlightAttributes in interface Attributable

isHighlighted

public boolean isHighlighted()

Description copied from interface: Highlightable

Indicates whether to highlight the shape.

Specified by:

isHighlighted in interface Highlightable

Returns:

true to highlight the shape, otherwise false.

setHighlighted

public void setHighlighted(boolean highlighted)

DrawContext

makeArrowhead

protected void makeArrowhead(DrawContext dc)

getReferencePosition

public Position getReferencePosition()

Description copied from interface: Movable2

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 Movable2

Returns:

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

moveTo

public void moveTo(Globe globe,
                   Position position)

Description copied from interface: Movable2

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

Specified by:

moveTo in interface Movable2

Parameters:

globe - the globe on which to move the shape.

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

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.

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.
