Class NodeType

java.lang.Object
  org.openanzo.common.rdb.layout.NodeType

public class NodeType
extends java.lang.Object

Provides allocation and conversion between RDF Node types and ids used by the node centric layout to reference them. Supports the various RDF Node types and subtypes: URI, LITERAL, Blank, Language and Datatype. Intended to be an internal component of the node layout package.
