Constructor Detail

ForwardLineOfOwnTroops

public ForwardLineOfOwnTroops(String sidc)

Create a new graphic.

Parameters:

sidc - MIL-STD-2525C identifier code.

Method Detail

computeDefaultWavelength

protected double computeDefaultWavelength(Iterable<? extends Position> positions,
                                          Globe globe)

computeGeometry

protected void computeGeometry(DrawContext dc)

Overrides:

computeGeometry in class AbstractTacticalGraphic

computeGreatCirclePathLength

protected Angle computeGreatCirclePathLength(Iterable<? extends Position> positions)

generateIntermediatePositions

protected void generateIntermediatePositions(DrawContext dc,
                                             Iterable<? extends Position> positions)

Generate the positions required to draw the polygon with a triangle wave boundary.

Parameters:

dc - Current draw context.

positions - Positions that define the polygon boundary.

generateWavePositions

protected List<Position> generateWavePositions(Iterator<? extends Position> iterator,
                                               double radius,

getGraphicLabel

protected String getGraphicLabel()

Overrides:

getIntervals

public int getIntervals()

Indicates the number of intervals used to draw the arc in this graphic.

Returns:

Intervals used to draw arc.

getPositions

public Iterable<? extends Position> getPositions()

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

Specified by:

getPositions in interface TacticalGraphic

Overrides:

getPositions in class PhaseLine

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.

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.

getWaveLength

public double getWaveLength()

Indicates the wavelength of the semicircle wave that forms the graphic's boundary. This is the length from the start of one "tooth" to the start of the next. If not wave length is specified a default wave length will be computed.

 ^ ^
 Wavelength
 

Returns:

The wave length, in meters.

moveTo

public void moveTo(Position position)

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

Specified by:

moveTo in interface Movable

Overrides:

moveTo in class AbstractTacticalGraphic

Parameters:

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

onShapeChanged

protected void onShapeChanged()

setIntervals

public void setIntervals(int intervals)

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

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

Specified by:

setPositions in interface TacticalGraphic

Overrides:

setPositions in class PhaseLine

Parameters:

positions - 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. The positions must be specified in the same order as the control points defined by the symbology set's template for this type of graphic.

setWaveLength

public void setWaveLength(int waveLength)

Specifies the wavelength of the triangle wave that forms the graphic's boundary. See getWaveLength() for more information on how this distance is interpreted.

Parameters:

waveLength - The wavelength, in meters.
