Class URIFactoryMemory

java.lang.Object

slib.graph.model.impl.repo.URIFactoryMemory

All Implemented Interfaces:

URIFactory

public final class URIFactoryMemory
extends Object
implements URIFactory

This class defines the singleton used as an in memory repository which manage all used URI and storage element i.e. graphs. The main goal of the DataFactory singleton is to avoid URI and NameSpace object duplicates and must therefore be used to create and load URIs. The repository must be in agreement to graph representation i.e. URI loaded in a graph are linked to the corresponding storage element in the Data repository. All change of the graph must be propagated on the Data Repository

Method Detail

getSingleton

public static URIFactoryMemory getSingleton()

Access to the in-memory URI Factory.

Returns:

the singleton

loadNamespacePrefix

public boolean loadNamespacePrefix(String prefix,
                          String reference)
                            throws SLIB_Ex_Critic

Specified by:

loadNamespacePrefix in interface URIFactory

Returns:

true if the prefix is loaded

Throws:

SLIB_Ex_Critic

getNamespace

public String getNamespace(String ns_prefix)

Specified by:

getNamespace in interface URIFactory

Returns:

the namespace associated to the prefix

clear

public void clear()

Specified by:

clear in interface URIFactory

getURI

public org.openrdf.model.URI getURI(String sURI)

Specified by:

getURI in interface URIFactory

getURI

public org.openrdf.model.URI getURI(String snamespace,
                           String sURI)

Specified by:

getURI in interface URIFactory

getURI

public org.openrdf.model.URI getURI(String sURI,
                           boolean useLoadedPrefix)

Description copied from interface: URIFactory

Loaded prefixes will be used, use URIFactory.getURI(java.lang.String) if loaded prefixes are not used. An URI with a prefix is for instance GO:xxxxx. Considering that GO is defined as PREFIX for http://go/ the URI will be http://go/xxxxx.

Specified by:

getURI in interface URIFactory

useLoadedPrefix - set to true loaded prefixes will be used.

Returns:

the URI

shortURIasString

public String shortURIasString(org.openrdf.model.URI uri)

Description copied from interface: URIFactory

Create a string representing the URI using the loaded prefixes if any can be used

Specified by:

shortURIasString in interface URIFactory

Parameters:

uri - the URI

Returns:

the URI as a string

getURIPrefixes

public Map<String,String> getURIPrefixes()

Specified by:

getURIPrefixes in interface URIFactory
