Examples of LayoutElement

com.sun.jsftemplating.layout.descriptors.LayoutElement
This interface is declares the methods required to be a LayoutElement. A LayoutElement is the building block of the tree structure which defines a layout for a particular component. There are different implementations of LayoutElement that provide various different types of functionality and data. Some examples are:
- Conditional ( {@link LayoutIf}), this allows portions of the layout tree to be conditionally rendered.
- Iterative ( {@link LayoutWhile}), this allows portions of the layout tree to be iteratively rendered.
- UIComponent ( {@link LayoutComponent}), this allows concrete UIComponents to be used. If the component doesn't already exist, it will be created automatically.
- Facet place holders ( {@link LayoutFacet}), this provides a means to specify where a facet should be rendered. It is not a facet itself but where a facet should be drawn. However, in addition, it may specify a default value if no facet was provided.

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
