Constructor Detail

DirectionOfAttack

public DirectionOfAttack(String sidc)

Create a new arrow graphic.

Parameters:

sidc - Symbol code the identifies the graphic.

Method Detail

applyDelegateOwner

protected void applyDelegateOwner(Object owner)

Invoked each frame to apply to the current delegate owner to all renderable objects used to draw the graphic. This base class will apply the delegate owner to Label objects. Subclasses must implement this method to apply the delegate owner to any Renderables that they will draw in order to render the graphic.

Specified by:

applyDelegateOwner in class AbstractTacticalGraphic

Parameters:

owner - Current delegate owner.

computeArrowheadPositions

protected List<Position> computeArrowheadPositions(DrawContext dc,
                                                   Vec4 tip,
                                                   Vec4 dir,
                                                   double length)

Determine the positions that make up the arrowhead.

Parameters:

dc - Current draw context.

tip - Point at the tip of the arrow head.

dir - Vector in the direction of the arrow head.

length - Length of the arrowhead from base to tip.

Returns:

Positions that define the arrowhead.

computeGeometry

protected void computeGeometry(DrawContext dc)

Overrides:

computeGeometry in class AbstractTacticalGraphic

createPath

protected Path createPath(List<Position> positions)

Create and configure the Path used to render this graphic.

Parameters:

positions - Positions that define the path.

Returns:

New path configured with defaults appropriate for this type of graphic.

createShapes

protected void createShapes(DrawContext dc)

Create the list of positions that describe the arrow.

Parameters:

dc - Current draw context.

doRenderGraphic

protected void doRenderGraphic(DrawContext dc)

Render this graphic, without modifiers.

Specified by:

doRenderGraphic in class AbstractTacticalGraphic

Parameters:

dc - Current draw context.

AbstractTacticalGraphic.doRenderTextModifiers(gov.nasa.worldwind.render.DrawContext), AbstractTacticalGraphic.doRenderGraphicModifiers(gov.nasa.worldwind.render.DrawContext)

getArrowAngle

public Angle getArrowAngle()

Indicates the angle of the arrowhead.

Returns:

Angle of the arrowhead in the graphic.

getArrowLength

public double getArrowLength()

Indicates the length of the arrowhead.

Returns:

The length of the arrowhead as a fraction of the total line length.

getOutlineWidth

public double getOutlineWidth()

Indicates the width of the arrowhead when it is drawn outlined. Note that the arrowhead is only drawn outlined when the graphic represents a Main Direction of Attack.

Returns:

Width of the outline as a fraction of the arrowhead length.

getPositions

public Iterable<? extends Position> getPositions()

Indicates the positions of the control points that place and orient the graphic.

Returns:

positions that orient the graphic. How many positions are returned depends on the type of graphic. Some graphics require only a single position, others require many.

getReferencePosition

public Position getReferencePosition()

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.

Returns:

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

getSupportedGraphics

public static List<String> getSupportedGraphics()

Indicates the graphics supported by this class.

Returns:

List of masked SIDC strings that identify graphics that this class supports.

isDrawOutlined

protected boolean isDrawOutlined()

Indicates whether or not to draw the arrow head outlined.

Returns:

true if the arrow head should be drawn outlined.

setArrowAngle

public void setArrowAngle(Angle arrowAngle)

Specifies the angle of the arrowhead in the graphic.

Parameters:

arrowAngle - The angle of the arrowhead. Must be greater than zero degrees and less than 90 degrees.

setArrowLength

public void setArrowLength(double arrowLength)

Specifies the length of the arrowhead.

Parameters:

arrowLength - Length of the arrowhead as a fraction of the total line length. If the arrowhead length is 0.25, then the arrowhead length will be one quarter of the total line length.

setOutlineWidth

public void setOutlineWidth(double outlineWidth)

Specifies the width of the the arrowhead when it is drawn outlined. Note that the arrowhead is only drawn outlined when the graphic represents a Main Direction of Attack.

Parameters:

outlineWidth - Width of the outline as a fraction of the length of the arrowhead.

setPositions

public void setPositions(Iterable<? extends Position> positions)

Specifies the positions of the control points that place and orient the graphic.

Parameters:

positions - Control points that orient the graphic. Must provide at least three points.
