Examples of org.gatein.api.navigation.Node.filter()

org.gatein.api.navigation.Node.filter()
Will return a filtered view of this navigation node. All child operations consider the filter.
For example if a node has 3 visible and one hidden children nodes and a filter is applied to only accept visible nodes, getChildrenCount would only return 2, iterating over the filtered node would not include the hidden node, etc.
@return a filtered node @throws IllegalArgumentException if filter is null

        Node node = getNode(NodePath.root(), true, visitor);
        boolean showAll = showAllAttribute != null && Boolean.parseBoolean(showAllAttribute);
        if (!showAll || !context.getExternalContext().isUserInRole("administrators")) {
            node = node.filter().showDefault();
        }


        return populateNavigationModel(node, scope, context);
    }
