Field Detail

positions

protected Iterable<? extends Position> positions

quad

protected SurfaceQuad quad

shapeInvalid

protected boolean shapeInvalid

Constructor Detail

AbstractRectangularGraphic

public AbstractRectangularGraphic(String sidc)

Create a new target.

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.

computeQuadSize

protected void computeQuadSize(DrawContext dc)

createShape

protected SurfaceQuad createShape()

doRenderGraphic

protected void doRenderGraphic(DrawContext dc)

Render the quad.

Specified by:

doRenderGraphic in class AbstractTacticalGraphic

Parameters:

dc - Current draw context.

See Also:

AbstractTacticalGraphic.doRenderTextModifiers(gov.nasa.worldwind.render.DrawContext), AbstractTacticalGraphic.doRenderGraphicModifiers(gov.nasa.worldwind.render.DrawContext)

getLength

public double getLength()

Indicates the length of the quad.

Specified by:

getLength in interface TacticalQuad

Returns:

The length of the quad, in meters.

getModifier

public Object getModifier(String modifier)

Indicates the current value of a text or graphic modifier.

Specified by:

getModifier in interface TacticalGraphic

Overrides:

getModifier in class AbstractMilStd2525TacticalGraphic

Parameters:

modifier - Key that identifies the modifier to retrieve. The possible modifiers depends on the symbol set.

Returns:

The value of the modifier, or null if the modifier is not set.

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

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.

getReferencePosition

public Position getReferencePosition()

A position associated with the object that indicates its aggregate geographic position. The chosen position varies among implementers of this interface. For objects defined by a list of positions, the reference position is typically the first position in the list. For symmetric objects the reference position is often the center of the object. In many cases the object's reference position may be explicitly specified by the application.

Specified by:

getReferencePosition in interface Movable

Returns:

the object's reference position, or null if no reference position is available.

getWidth

public double getWidth()

Indicates the width of the quad.

Specified by:

getWidth in interface TacticalQuad

Returns:

The width of the quad, in meters.

preRender

public void preRender(DrawContext dc)

Specified by:

preRender in interface PreRenderable

setLength

public void setLength(double length)

Specifies the length of the quad.

Specified by:

setLength in interface TacticalQuad

Parameters:

length - New length, in meters.

setModifier

public void setModifier(String modifier,
                        Object value)

Specifies the value of a text or graphic modifier.

Specified by:

setModifier in interface TacticalGraphic

Overrides:

setModifier in class AbstractMilStd2525TacticalGraphic

Parameters:

modifier - Key that identifies the modifier to set. The possible modifiers depends on the symbol set.

value - New value for the modifier.

setPositions

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

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

Specified by:

setPositions in interface TacticalGraphic

Parameters:

positions - Control points. This graphic uses only two control point, which determine the midpoints of two opposite sides of the quad. See Fire Support Area (2.X.4.3.2.1.2) on pg. 652 of MIL-STD-2525C for an example of how these points are interpreted.

setWidth

public void setWidth(double width)

Specifies the width of the quad.

Specified by:

setWidth in interface TacticalQuad

Parameters:

width - New width, in meters.
