The NodeURL class is one of the subclass of PortalURL that is specialized in navigation node resources:

public class NodeURL extends PortalURL<NavigationResource, NodeURL>

{

   ...

}

The NodeURL class does not carry any generic types of its super class, which means that a NodeURL is type-safe and you do not have to worry about generic types.

Using a NodeURL is pretty straightforward:

NodeURL url = RequestContext.getCurrentInstance().createURL(NodeURL.TYPE);

url.setResource(new NavigationResource("portal", "classic, "home"));

String s = url.toString();

The NodeURL subclass contains the specialized setter methods to make its usage even easier:

UserNode node = ...;

NodeURL url = RequestContext.getCurrentInstance().createURL(NodeURL.TYPE);

url.setNode(node);

String s = url.toString();
