Package javax.faces.component.visit Description

APIs for traversing a user interface component view.

The following example visits all nodes in the view.

  1. UIViewRoot root = facesContext.getViewRoot();
  2. root.visitTree(VisitContext.createVisitContext(context),
  3.                new VisitCallback() {
  4.                    public VisitResult visit(VisitContext context,
  5.                                             UIComponent target) {
  6.                        // take some action on target
  7.                        return VisitResult.ACCEPT;
  8.                    }
  9.                });

The following example visits two subtrees within the component view.

  1. Set<String> toVisit = getSet("form1:optionsPanel", "form2:detailPanel");
  2. UIViewRoot root = facesContext.getViewRoot();
  3. root.visitTree(VisitContext.createVisitContext(context, toVisit, null),
  4.                new VisitCallback() {
  5.                    public VisitResult visit(VisitContext context,
  6.                                             UIComponent target) {
  7.                        // take some action on target
  8.                        return VisitResult.ACCEPT;
  9.                    }
  10.                });

Note that every child node of those two subtrees is visited.
