RBlock

java.lang.Object
- org.lobobrowser.html.renderer.RBlock

All Implemented Interfaces:

java.awt.image.ImageObserver, UINode, BoundableRenderable, RCollection, RElement, Renderable, RenderableContainer
```
public class RBlock
extends java.lang.Object
implements RenderableContainer, java.awt.image.ImageObserver
```
Represents a HTML block in a rendered document, typically a DIV. The root renderer node is of this type as well.
Immediately below an RBlock you will find a node of type RBlockViewport.
