Class PrintUtil

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

public class PrintUtil
extends java.lang.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.

Method Summary

static java.lang.String	expandQname(java.lang.String uri) Expand qnames to URIs.
static void	init() Load built in prefixes.
static java.lang.String	print(Node node) Return a simplified print string for a Node.
static java.lang.String	print(java.lang.Object obj) Default print which just uses tostring

Method Detail

init

public static void init()

Load built in prefixes.

registerPrefix

public static void registerPrefix(java.lang.String prefix,
                                  java.lang.String namespace)

Register a new prefix/namespace mapping which will be used to shorten the print strings for resources in known namespaces.

registerPrefixMap

public static void registerPrefixMap(java.util.Map<java.lang.String,java.lang.String> map)

Register a set of new prefix/namespace mapping which will be used to shorten the print strings for resources in known namespaces.

removePrefix

public static void removePrefix(java.lang.String prefix)

Remove a registered prefix from the table of known short forms

removePrefixMap

public static void removePrefixMap(java.util.Map<java.lang.String,java.lang.String> map)

Remove a set of prefix mappings from the table of known short forms

print

public static java.lang.String print(Node node)

Return a simplified print string for a Node.

print

public static java.lang.String print(RDFNode node)

Return a simplified print string for an RDFNode.

print

public static java.lang.String print(Triple triple)

Return a simplified print string for a Triple

print

public static java.lang.String print(TriplePattern triple)

print

public static java.lang.String print(Statement stmt)

print

public static java.lang.String print(java.lang.Object obj)

                               int indent)

Print an n-space indent to the given output stream

printOut

public static void printOut(java.util.Iterator<?> it)

Print all the Triple values from a find iterator.
