Class PrefixMapExtended

java.lang.Object
  org.apache.jena.riot.system.PrefixMapBase
      org.apache.jena.riot.system.PrefixMapExtended

All Implemented Interfaces:

PrefixMap

public class PrefixMapExtended
extends PrefixMapBase

Implementation of a PrefixMap which extends another prefix map without ever altering the parent.

This allows code to modify a prefix map based off of another map without modifying that original map. This is somewhat different than simply making a copy of an existing map since this implementation is partly a view over another map so will reflect changes that happen to the other map.

Constructor Summary

PrefixMapExtended(PrefixMap ext)
Creates an extended prefix map

Method Summary

Pair<String,String>	abbrev(String uriStr) Abbreviate an IRI and return a pair of prefix and local parts, or null.
String	abbreviate(String uriStr) Abbreviate an IRI or return null
void	add(String prefix, org.apache.jena.iri.IRI iri) Add a prefix, overwrites any existing association
boolean	contains(String prefix) Gets whether the map contains a given prefix
void	delete(String prefix) Delete a prefix
String	expand(String prefix, String localName) Expand a prefix, return null if it can't be expanded
Map<String,org.apache.jena.iri.IRI>	getMapping() Return the underlying mapping, this is generally unsafe to modify and implementations may opt to return an unmodifiable view of the mapping if they wish
boolean	isEmpty() return whether the
int	size() Return the number of entries in the prefix map.
