public class TreeNode extends TreeFamily
UIComponent that represents a single tree node within a parent
Tree component. Within this component, the var attribute of the parent Tree
component will expose the tree node. Each of its children is processed by TreeNodeItem.
The level attribute can be used to specify for which tree node level as obtained by
TreeModel.getLevel() this component should render the children by TreeNodeItem. The root tree node
has level 0.

Returns the level for which this node should render the items.

process(FacesContext context,
PhaseId phaseId)
This method is by design only called by
Tree.processTreeNode(FacesContext, PhaseId) as it maintains all
the nodes. |

setLevel(Integer level)
Sets the level for which this node should render the items.
