Field Detail

additionalText

protected String additionalText

The value of an optional second text string for the graphic. This value is equivalent to the "T1" modifier defined by MIL-STD-2525C. It can be set using setAdditionalText(String), or by passing an Iterable to setModifier(String, Object) with a key of SymbologyConstants.UNIQUE_DESIGNATION (additional text is the second value in the iterable).

BOTTOM_LABEL_OFFSET

protected static final Offset BOTTOM_LABEL_OFFSET

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

DEFAULT_VERTICAL_LENGTH

public static final double DEFAULT_VERTICAL_LENGTH

Default length of the arrowhead, as a fraction of the total line length.

Constant Field Values

endPosition

protected Position endPosition

Second control point.

paths

protected Path[] paths

Paths used to render the graphic.

startPosition

protected Position startPosition

First control point.

TOP_LABEL_OFFSET

protected static final Offset TOP_LABEL_OFFSET

Offset applied to the graphic's upper 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.

verticalLength

protected double verticalLength

Length of the vertical segments, as a fraction of the horizontal segment.

Constructor Detail

LinearTarget

public LinearTarget(String sidc)

Create a new target 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.

computeVerticalSegmentPositions

protected List<Position> computeVerticalSegmentPositions(Globe globe,
                                                         Vec4 basePoint,
                                                         Vec4 segment,
                                                         double verticalLength)

Compute positions for one of the vertical segments in the graphic.

Parameters:

getModifier

public Object getModifier(String key)

Description copied from class: AbstractMilStd2525TacticalGraphic

Indicates the current value of a text or graphic modifier.

Specified by:

getModifier in interface TacticalGraphic

Overrides:
