com.hp.hpl.jena.graph.Node
A Node has five subtypes: Node_Blank, Node_Anon, Node_URI, Node_Variable, and Node_ANY. Nodes are only constructed by the node factory methods, and they will attempt to re-use existing nodes with the same label if they are recent enough. @author Jeremy Carroll and Chris Dollin
