    Description copied from class: StaticRenderer
    
    Flush a rectangle of cached image data.
    
    Specified by:
    
    flush in interface ImageRenderer

public void flush(java.util.Collection areas)
```
    Flush a list of rectangles of cached image data.
    
    Specified by:
    
    flush in interface ImageRenderer
    
    Overrides:
    
    flush in class StaticRenderer
  - updateWorkingBuffers
```
protected void updateWorkingBuffers()
```
    Description copied from class: StaticRenderer
    
    Internal method used to synchronize local state in response to various set methods.
    
    Overrides:
    
    updateWorkingBuffers in class StaticRenderer
  - repaint
```
public void repaint(RectListManager devRLM)
```
    Repaints the associated GVT tree under the list of areas. If double buffered is true and this method completes cleanly it will set the result of the repaint as the image returned by getOffscreen otherwise the old image will still be returned. If double buffered is false it is possible some effects of the failed rendering will be visible in the image returned by getOffscreen.
    
    Specified by:
    
    repaint in interface Renderer
    
    Overrides:
    
    repaint in class StaticRenderer
    
    Parameters:
    devRLM - regions to be repainted, in the current user space coordinate system.
