public class PrintUtil
extends Object

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

init

public static void init()

Load built in prefixes.

registerPrefix

public static void registerPrefix(String prefix,
 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(Map<String,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(String prefix)

Remove a registered prefix from the table of known short forms

removePrefixMap

public static void removePrefixMap(Map<String,String> map)

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

print

public static String print(Node node)

Return a simplified print string for a Node.

print

public static String print(RDFNode node)

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)

Return a simplified print string for a TriplePattern

print

public static String print(Statement stmt)

Return a simplified print string for a statement

print

public static String print(Object obj)

Default print which just uses tostring

expandQname

printOut

public static void printOut(Iterator<?> it)

Print all the Triple values from a find iterator.
