Field Detail

computedPositions

protected java.util.List<Position> computedPositions

Positions computed from the original positions. This list includes the positions necessary to draw the square wave.

DEFAULT_NUM_WAVES

public static final int DEFAULT_NUM_WAVES

Default number of wave lengths for a simple shape. This number is used to compute a default wave length.

See Also:

Constant Field Values

positions

protected java.lang.Iterable<? extends Position> positions

Original positions specified by the application.

waveLength

protected double waveLength

Indicates the wavelength of the square wave that forms the graphic's border.

Constructor Detail

FortifiedArea

public FortifiedArea(java.lang.String sidc)

Method Detail

computeDefaultWavelength

protected double computeDefaultWavelength(Globe globe)

Compute a default tooth size for the polygon. This method computes the default wavelength as a function of the size of the polygon and the number of vertices. As the polygon gets bigger the wavelength will increase, but as the number of the vertices increases the wavelength will decrease to prevent the waves from obscuring the shape of the polygon.

Parameters:

globe - Globe on which the area will be rendered.

Returns:

The wave length.

computeGeometry

public void computeGeometry(DrawContext dc)

Overrides:

computeGeometry in class AbstractTacticalGraphic

generateIntermediatePositions

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

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

Parameters:

dc - Current draw context.

positions - Positions that define the polygon boundary.

getPositions

public java.lang.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 BasicArea

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 java.util.List<java.lang.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 square wave that forms the graphic's boundary. This is the length from the start of one square "tooth" to the start of the next.

    __    __
 __|  |__|  |__
   ^     ^
   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.

setPositions

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

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

Specified by:

setPositions in interface TacticalGraphic

Overrides:

setPositions in class BasicArea

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(double waveLength)

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

Parameters:

waveLength - The wavelength, in meters.
