Field Detail

curvature

protected double curvature

Factor that controls the curve of the line. Valid values are 0 to 1. Larger values result in a more pronounced curve.

DASHED_LINE_DISTANCE

protected static final double DASHED_LINE_DISTANCE

Factor used to compute the distance between the solid and dashed lines in the arrow head. A larger value will move the dashed line farther from the solid line.

See Also:

Constant Field Values

dashedAttributes

protected ShapeAttributes dashedAttributes

Shape attributes for the dashed part of the graphic.

DEFAULT_ARROWHEAD_ANGLE

public static final Angle DEFAULT_ARROWHEAD_ANGLE

Default angle of the arrowhead.

DEFAULT_CURVATURE

public static final double DEFAULT_CURVATURE

Default factor that determines the curvature of the line.

See Also:

Constant Field Values

DEFAULT_NUM_INTERVALS

public static final int DEFAULT_NUM_INTERVALS

Default number of intervals used to draw the curve.

See Also:

Constant Field Values

intervals

protected int intervals

Number of intervals used to draw the curve.

LABEL_OFFSET

protected static final Offset LABEL_OFFSET

Offset applied to the label. This offset aligns the bottom edge of the label with the geographic position, in order to keep the label above the graphic as the zoom changes.

labelOrientationPosition

protected Position labelOrientationPosition

Orientation position for the label. (The label is drawn on a line between this position and labelPosition.

labelPosition

protected Position labelPosition

Position of the label along the curve.

Constructor Detail

DirectionOfAttackForFeint

public DirectionOfAttackForFeint(java.lang.String sidc)

Create a new arrow graphic.

Parameters:

sidc - Symbol code the identifies the graphic.

Method Detail

computeBezierControlPoints

protected Vec4[] computeBezierControlPoints(DrawContext dc,
                                            Vec4 start,
                                            Vec4 end,
                                            double curvature)

Compute the position of control points that will generate a Bezier curve that looks like the Direction of Attack for Feint graphic in MIL-STD-2525C (pg. 499).

Parameters:

dc - Current draw context.

start - Beginning of the infiltration lane control line.

end - End of the infiltration lane control line.

curvature - Factor that controls the curvature of the line. Valid values are between zero and one. A higher value results in a more pronounced curve.

Returns:

Control points for a Bezier curve. The first control point is equal to start, and the last point is equal to end.

createLabels

protected void createLabels()

Overrides:

createLabels in class AbstractTacticalGraphic

createShapes

protected void createShapes(DrawContext dc)

Create the list of positions that describe the arrow.

Overrides:

createShapes in class DirectionOfAttack

Parameters:

determineActiveAttributes

protected void determineActiveAttributes()

Determine active attributes for this frame.

Overrides:

determineActiveAttributes in class AbstractTacticalGraphic

determineLabelPositions

protected void determineLabelPositions(DrawContext dc)

Description copied from class: AbstractTacticalGraphic

Determine positions for the start and end labels.

Overrides:

determineLabelPositions in class AbstractTacticalGraphic

Parameters:

dc - Current draw context.

getCurvature

public double getCurvature()

Indicates a factor that determines the curvature of the line. Valid values are zero to one. A large value results in a more pronounced curve.

Returns:

The factor that determines the curvature of the line.

getDefaultLabelOffset

protected Offset getDefaultLabelOffset()

Indicates the default offset applied to the graphic's main label. This offset may be overridden by the graphic attributes.

Overrides:

getDefaultLabelOffset in class AbstractTacticalGraphic

Returns:

Offset to apply to the main label.

getIntervals

public int getIntervals()

Indicates the number of intervals used to draw the curve in this graphic. More intervals results in a smoother curve.

Indicates the graphics supported by this class.

Returns:

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

onShapeChanged

protected void onShapeChanged()

setCurvature

public void setCurvature(double factor)

Specifies a factor that determines the curvature of the line. Valid values are zero to one. A large value results in a more pronounced curve.

Parameters:

factor - The factor that determines the curvature of the line.

setIntervals

public void setIntervals(int intervals)

Specifies the number of intervals used to draw the curve in this graphic. More intervals will result in a smoother looking curve.

Parameters:

intervals - Number of intervals for drawing the curve. Must at least three.
