Field Detail

DEFAULT_OFFSET

protected static final Offset DEFAULT_OFFSET

orientationPosition

protected Position orientationPosition

The label is drawn along a line from the label position to the orientation position.

rotation

protected Angle rotation

Rotation to apply to symbol, computed each frame.

sidc

protected String sidc

Identifier for this graphic.

Constructor Detail

EchelonSymbol

public EchelonSymbol(String sidc)

Constructs a new symbol with the specified position. The position specifies the latitude, longitude, and altitude where this symbol is drawn on the globe. The position's altitude component is interpreted according to the altitudeMode.

Parameters:

sidc - MIL-STD-2525C sidc code.

Throws:

IllegalArgumentException - if sidc is null, or does not contain a value for the Echelon field.

Method Detail

assembleIconRetrieverParameters

protected AVList assembleIconRetrieverParameters(AVList params)

Overrides:

assembleIconRetrieverParameters in class AbstractTacticalSymbol

computeRotation

protected Angle computeRotation(Vec4 screenPoint,
                                Vec4 orientationScreenPoint)

Compute the amount of rotation to apply to a label in order to keep it oriented toward its orientation position.

Parameters:

screenPoint - Geographic position of the text, projected onto the screen.

orientationScreenPoint - Orientation position, projected onto the screen.

Returns:

The rotation angle to apply when drawing the label.

computeTransform

protected void computeTransform(DrawContext dc)

Overrides:

computeTransform in class AbstractTacticalSymbol

drawIcon

protected void drawIcon(DrawContext dc)

Overridden to apply rotation.

Overrides:

drawIcon in class AbstractTacticalSymbol

getIdentifier

public String getIdentifier()

Indicates a string identifier for this symbol. The format of the identifier depends on the symbol set to which this symbol belongs. For symbols belonging to the MIL-STD-2525 symbol set, this returns a 15-character alphanumeric symbol identification code (SIDC).

Returns:

an identifier for this symbol.

getOrientationPosition

public Position getOrientationPosition()

Indicates the orientation position. The label oriented on a line drawn from the label's position to the orientation position.

Returns:

Position used to orient the label. May be null.

setOrientationPosition

public void setOrientationPosition(Position orientationPosition)

Specifies the orientation position. The label is oriented on a line drawn from the label's position to the orientation position. If the orientation position is null then the label is drawn with no rotation.

Parameters:

orientationPosition - Draw label oriented toward this position.
