protected void determineLabelPositions(DrawContext dc)
```
    Determine positions for the start and end labels.
    
    Parameters:
    
    dc - Current draw context.
  - createLabels
```
protected void createLabels()
```
  - addLabel
```
protected TacticalGraphicLabel addLabel(java.lang.String text)
```
  - computeGeometry
```
protected void computeGeometry(DrawContext dc)
```
  - determineDelegateOwner
```
protected void determineDelegateOwner()
```
    Determine the delegate owner for the current frame, and apply the owner to all renderable objects used to draw the graphic.
  - getActiveDelegateOwner
```
protected java.lang.Object getActiveDelegateOwner()
```
    Indicates the object attached to the pick list to represent this graphic.
    
    Returns:
    
    Delegate owner, if specified, or this if an owner is not specified.
  - determineActiveAttributes
```
protected void determineActiveAttributes()
```
    Determine active attributes for this frame.
  - applyLabelAttributes
```
protected void applyLabelAttributes()
```
    Apply the active attributes to the graphic's labels.
  - computeLabelInteriorOpacity
```
protected double computeLabelInteriorOpacity(double textOpacity)
```
    Compute the opacity for the label interior. By default, the label interior is opacity is computed as 70% of the text opacity.
    
    Parameters:
    
    textOpacity - Opacity of the label text.
    
    Returns:
    
    Opacity of the label interior as a floating point number between 0.0 and 1.0.
  - getDefaultLabelOffset
```
protected Offset getDefaultLabelOffset()
```
    Indicates the default offset applied to the graphic's main label. This offset may be overridden by the graphic attributes.
    
    Returns:
    
    Offset to apply to the main label.
  - getActiveOverrideAttributes
```
protected TacticalGraphicAttributes getActiveOverrideAttributes()
```
    Get the override attributes that are active for this frame.
    
    Returns:
    
    Override attributes. Values set in this bundle override defaults specified by the symbol set.
  - getActiveShapeAttributes
```
protected ShapeAttributes getActiveShapeAttributes()
```
    Get the active shape attributes for this frame. The active attributes are created by applying application specified overrides to the default attributes specified by the symbol set.
    
    Returns:
    
    Active shape attributes.
  - getLabelMaterial
```
protected Material getLabelMaterial()
```
    Get the Material that should be used to draw labels. If no override material has been specified, the graphic's outline Material is used for the labels.
    
    Returns:
    
    The Material that should be used when drawing labels. May change each frame.
  - applyDefaultAttributes
```
protected void applyDefaultAttributes(ShapeAttributes attributes)
```
    Apply defaults to the active attributes bundle. The default attributes are determined by the type of graphic. This method is called each frame to reset the active shape attributes to the appropriate default state. Override attributes specified by the application may be applied after the defaults have been set.
    
    Parameters:
    
    attributes - Attributes bundle to receive defaults.
  - applyOverrideAttributes
```
protected void applyOverrideAttributes(TacticalGraphicAttributes graphicAttributes,
                                       ShapeAttributes shapeAttributes)
```
    Apply override attributes specified in a TacticalGraphicAttributes bundle to the active ShapeAttributes. Any non-null properties of graphicAttributes will be applied to shapeAttributes.
    
    Parameters:
    
    graphicAttributes - Override attributes.
    
    shapeAttributes - Shape attributes to receive overrides.
