Class Uri

java.lang.Object
  org.mulgara.mrg.Uri

All Implemented Interfaces:

Comparable<Node>, Node, ObjectNode, PredicateNode, SubjectNode

public class Uri
extends Object
implements SubjectNode, PredicateNode, ObjectNode

A wrapper for a URI. This allows the use of URI as a Node. TODO: create Uri with factory from the graph. If a uri string is already internal (u == u.intern()) then it is already in the graph, and we want to find it with the existing indexes so that we can reuse the object.

Field Summary

static int

TYPE_ID The type identifier for Uri

Constructor Summary

Uri(String u)
Convenience to a new URI.

Uri(URI uri)
Create a new URI.

Method Summary

int	compareTo(Node o) Compares this object with the specified object for order.
static Uri	create(String u) Safe creation of a URI.
boolean	equals(Object o) Equality method.
int	getTypeId() A type identifier to distinguish from the other types of Node.
URI	getURI() Gets the wrapped URI.
int	hashCode() The hashcode, based on the uri.
String	toString() Represents this node as a string.
