Field Detail

circle

protected SurfaceCircle circle

Constructor Detail

AbstractCircularGraphic

public AbstractCircularGraphic(java.lang.String sidc)

Create a new circular area.

Parameters:

sidc - Symbol code the identifies the graphic.

Method Detail

applyDelegateOwner

protected void applyDelegateOwner(java.lang.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.

createShape

protected SurfaceCircle createShape()

determineActiveAttributes

protected void determineActiveAttributes()

Determine active attributes for this frame. Overridden to apply the delegate owner to shapes used to draw the circle.

Overrides:

determineActiveAttributes in class AbstractTacticalGraphic

doRenderGraphic

protected void doRenderGraphic(DrawContext dc)

Render the polygon.

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)

getModifier

public java.lang.Object getModifier(java.lang.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.

getPosition

public Position getPosition()

Indicates the position of the graphic.

Specified by:

getPosition in interface TacticalPoint

Returns:

The position of the graphic.

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

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.

getRadius

public double getRadius()

Indicates the radius of this circle. Calling this method is equivalent to calling getModifier(SymbologyConstants.DISTANCE ).

Specified by:

getRadius in interface TacticalCircle

Returns:

The radius of this circle, in meters.

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.

preRender

public void preRender(DrawContext dc)

Specified by:

preRender in interface PreRenderable

reset

protected void reset()

Invoked when the position or radius of the circle changes. This implementation does nothing, but subclasses can override to invalid state when the graphic is changed.

setModifier

public void setModifier(java.lang.String modifier,
                        java.lang.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.

setPosition

public void setPosition(Position position)

Specifies the position of the graphic.

Specified by:

setPosition in interface TacticalPoint

Parameters:

position - New 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

Parameters:

positions - Control points. This graphic uses only one control point, which determines the center of the circle.

setRadius

public void setRadius(double radius)

Specifies the radius of this circle. Calling this method is equivalent to calling setModifier(SymbologyConstants.DISTANCE, value).

Specified by:

setRadius in interface TacticalCircle

Parameters:

radius - New radius, in meters.
