public class VirtualNodeManager
extends AbstractNodeManager
implements NodeManager

This class represents a virtual node type information object. It has the same functionality as BasicNodeType, but it's nodes are vitrtual - that is, constructed based on the results of a search over multiple node managers. As such, it is not possible to search on this node type, nor to create new nodes. It's sole function is to provide a type definition for the results of a search.
