Direct Known Subclasses:

public abstract class ImageRenderer
extends Renderer

Since Graphics can draw image, It's possible to render all cacheable component individually, then assemble them together.

The rendering steps:

1. Rendering all modified cacheable components
2. Assembling result of 1st step into a final result
3. notify all registered RenderingFinishedListener

A renderer maintains a cache for all cacheable components. The cache is a map, the key is uid of components, the value is components future. The environment must offer those values when calling a renderer

1. all cacheable components and their uid in assembly order
2. all uid of unmodified cacheable components

Render the given plot. This method is protected by environment lock.

Specified by:

render in class Renderer

Parameters:

comp - the component to be rendered

cacheBlockList - A list of CacheBlock in z-order, contains the top component, even if the component is uncacheable. The CacheBlock contains cacheable components that will be rendered.
