public class TreeNodeItem
extends TreeFamily

TreeNodeItem is an UIComponent that represents a single child tree node within a parent TreeNode component. Within this component, the var attribute of the parent Tree component will expose the child tree node.

This component allows a child component of type TreeInsertChildren which indicates the place to insert the children of the current child tree node recursively by a TreeNode component associated with the children's level in the same parent Tree component.

Method Summary

void	encodeAll(javax.faces.context.FacesContext context) Suppress default behavior of encodeAll(FacesContext) (which also checks UIComponentBase.isRendered()) by delegating directly to TreeFamily.encodeChildren(FacesContext).
protected void	process(javax.faces.context.FacesContext context, javax.faces.event.PhaseId phaseId) Loop over children of the current model node, set the child as the current model node and continue processing this component according to the rules of the given phase ID.
protected void	validateHierarchy() Validate the component hierarchy.
boolean	visitTree(javax.faces.component.visit.VisitContext context, javax.faces.component.visit.VisitCallback callback) Loop over children of the current model node, set the child as the current model node and continue visiting this component according to the given visit context and callback.

Method Detail

validateHierarchy

protected void validateHierarchy()

Validate the component hierarchy.

Specified by:

validateHierarchy in class TreeFamily

Throws:

java.lang.IllegalArgumentException - When there is no parent of type Tree, or when this component is nested in another TreeNodeItem.

encodeAll

public void encodeAll(javax.faces.context.FacesContext context)
               throws java.io.IOException

Suppress default behavior of encodeAll(FacesContext) (which also checks UIComponentBase.isRendered()) by delegating directly to TreeFamily.encodeChildren(FacesContext).

Overrides:

encodeAll in class javax.faces.component.UIComponent

Throws:

java.io.IOException

process

protected void process(javax.faces.context.FacesContext context,
                       javax.faces.event.PhaseId phaseId)

Loop over children of the current model node, set the child as the current model node and continue processing this component according to the rules of the given phase ID.

Specified by:

process in class TreeFamily

Parameters:

context - The faces context to work with.

phaseId - The current phase ID.

See Also:

Tree.setCurrentModelNode(FacesContext, TreeModel)

visitTree

public boolean visitTree(javax.faces.component.visit.VisitContext context,
                         javax.faces.component.visit.VisitCallback callback)

Loop over children of the current model node, set the child as the current model node and continue visiting this component according to the given visit context and callback.

Overrides:

visitTree in class javax.faces.component.UIComponent

Parameters:

context - The visit context to work with.

callback - The visit callback to work with.
