Class PrintUtil

java.lang.Object
  extended by com.hp.hpl.jena.util.PrintUtil

public class PrintUtil
extends Object

A collection of small utilites for pretty printing nodes, triples and associated things. The core functionality here is a static prefix map which is preloaded with known prefixes.

updated by Chris March 2004 to use a PrefixMapping rather than the specialised tables.

Return a simplified print string for an RDFNode.


print

public static String print(Triple triple)
Return a simplified print string for a Triple


print

public static String print(TriplePattern triple)
