Constructor Detail

AttackByFirePosition

public AttackByFirePosition(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,
                                                   Position base,
                                                   Position tip)

Determine the positions that make up the arrowhead.

Parameters:

dc - Current draw context.

base - Position of the arrow's starting point.

tip - Position of the arrow head tip.

Returns:

Positions that define the arrowhead.

computeBasePositions

protected List<Position> computeBasePositions(DrawContext dc,
                                              Position position1,
                                              Position position2,
                                              Position orientationPos)

Determine the positions that make up the base of the graphic (a trapezoid missing one side).

Parameters:

dc - Current draw context.

position1 - The first control point that defines the graphic base.

position2 - The second control point that defines the graphic base.

orientationPos - A point on the arrow head side of the graphic. The legs of the base will point away from this position.

Returns:

Positions that define the graphic's base.

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.

protected void createShapes(DrawContext dc)

Create the paths required to draw the graphic.

Parameters:

dc - Current draw context.

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.

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.

setArrowLength

public void setArrowLength(double arrowLength)

Specifies the length of the arrowhead.

setLegLength

public void setLegLength(double legLength)

Specifies the length of the legs of the graphic's base.

Parameters:

legLength - Length of the legs of the graphic's base, as a fraction of the distance between the control points that define the base.
