Package org.apache.jena.dboe.storage

Interface StoragePrefixes

All Known Implementing Classes:

StoragePrefixesEmpty, StoragePrefixesSimpleMem

public interface StoragePrefixes

Like PrefixMapping, only for a dataset which can have different prefix maps for different graphs. There is a distinguished name Prefixes.nodeDataset that means the prefixes apply to the dataset as a whole, not a specific graph.

Method Summary

Modifier and Type	Method	Description
void	add(Node graphNode, String prefix, String iriStr)	Add a prefix, overwrites any existing association
void	delete(Node graphNode, String prefix)	Delete a prefix mapping
void	deleteAll(Node graphNode)	Delete prefix mappings for a specific graph name.
Iterator<PrefixEntry>	get(Node graphNode)
String	get(Node graphNode, String prefix)
boolean	isEmpty()	Return whether there are any prefix mappings or not (any graph).
Iterator<Node>	listGraphNodes()
default Iterator<org.apache.jena.atlas.lib.Pair<Node,PrefixEntry>>	listMappings()	All the mappings.
int	size()	Return the number of mappings.

Method Details

get

String get(Node graphNode,
 String prefix)

get

Iterator<PrefixEntry> get(Node graphNode)

listGraphNodes

Iterator<Node> listGraphNodes()

add

void add(Node graphNode,
 String prefix,
 String iriStr)

Add a prefix, overwrites any existing association

delete

void delete(Node graphNode,
