org.jfree.layouting.layouter.model.LayoutElement
Represents a DOM element. The tree is only backward-traversable; non-element nodes are not traversable at all.
All nodes hold a reference to their parent and all elements also hold a reference to their preceeding silbling nodes. This structure guarantees a minimal memory footprint, as nodes automaticly get garbage collected as soon as they have been fully processed. Manual cleaning is not needed.
This theory vanishes as soon as we enter the 'pinned' mode. In that mode, each element holds strong references to all of its childs. These childs do not go out of context unless the first pinned element does. @author Thomas Morgner
