Class GraphRegistry

java.lang.Object
  org.topbraid.core.registry.impl.GraphRegistry

All Implemented Interfaces:

IGraphRegistry

public class GraphRegistry
extends java.lang.Object
implements IGraphRegistry

Method Detail

addListener

public void addListener(IGraphRegistryListener listener)

Specified by:

addListener in interface IGraphRegistry

dispose

public void dispose()

Specified by:

dispose in interface IGraphRegistry

disposeConfigModel

public void disposeConfigModel(java.net.URI baseURI)

dump

public void dump(java.io.PrintStream ps)

getBaseGraph

public com.hp.hpl.jena.graph.Graph getBaseGraph(com.hp.hpl.jena.graph.Graph perhapsDelegatingGraph)

getBaseURI

public java.net.URI getBaseURI(java.io.File file)

Specified by:

getBaseURI in interface IGraphRegistry

getBaseURI

public java.net.URI getBaseURI(org.eclipse.core.resources.IFile file)

Specified by:

getBaseURI in interface IGraphRegistry

getBaseURI

public java.net.URI getBaseURI(com.hp.hpl.jena.graph.Graph graph)

Specified by:

getBaseURI in interface IGraphRegistry

getConfigModel

public com.hp.hpl.jena.rdf.model.Model getConfigModel(java.net.URI baseURI)

Description copied from interface: IGraphRegistry

Gets the configuration Model that holds metadata for a given Model. Note: This is work in progress and should not be used yet externally.

Specified by:

getConfigModel in interface IGraphRegistry

Parameters:

baseURI - the URI to get the config Model for

Returns:

the Config Model or null for any unregistered baseURI

getConfigOntModel

public com.hp.hpl.jena.ontology.OntModel getConfigOntModel(java.net.URI baseURI)

Description copied from interface: IGraphRegistry

Gets the OntModel that contains all configuration models of subgraphs as well as the base config model and system configuration models.

Specified by:

getConfigOntModel in interface IGraphRegistry

Parameters:

baseURI - the URI to get the OntModel for

Returns:

the Config Model or null for any unregistered baseURI

getBaseGraph

public com.hp.hpl.jena.graph.Graph getBaseGraph(java.net.URI baseURI)

Specified by:

getBaseGraph in interface IGraphRegistry

getImportBaseURI

public java.net.URI getImportBaseURI(java.net.URI importedURI)

Description copied from interface: IGraphRegistry

Gets the base URI of an ontology specified by an import statement. This will first check if the URI is already registered in this ModelRegistry, e.g. when it has been loaded from a file. Otherwise, the method will resolve the URI into a URL and consult the URLRegistry to determine whether the URL can be opened to find a declared xml:base.

Specified by:

getImportBaseURI in interface IGraphRegistry

Parameters:

importedURI - the imported URI (object of an owl:imports statement)

Returns:

the URI (often identical to importedURI)

getSource

public java.lang.Object getSource(java.net.URI baseURI)

Description copied from interface: IGraphRegistry

Gets the source where a Graph (represented by its base URI) has been loaded from. If the model was loaded using the ModelLoader, then this will return one of:

• URL, if the model was imported from the Web
• IFile, if the model was loaded from a file in the workspace
• File, if the model was loaded from a file outside of the workspace

Specified by:

getSource in interface IGraphRegistry

Parameters:

baseURI - the base URI of the model

Returns:

the source (IFile, java.io.File, or URL) or null

initConfigModel

public void initConfigModel(java.net.URI baseURI)

invalidateConfigOntModels

public void invalidateConfigOntModels()

isDirty

public boolean isDirty(com.hp.hpl.jena.graph.Graph graph)

Specified by:

isDirty in interface IGraphRegistry

isMemoryGraph

public boolean isMemoryGraph(com.hp.hpl.jena.graph.Graph graph)

Specified by:

isMemoryGraph in interface IGraphRegistry

listURIs

public java.util.Iterator<java.net.URI> listURIs()

Description copied from interface: IGraphRegistry

Lists the URIs of all currently loaded graphs.

Specified by:

listURIs in interface IGraphRegistry

Returns:

the open graph URIs

register

public com.hp.hpl.jena.graph.Graph register(java.net.URI baseURI,
                                            com.hp.hpl.jena.graph.Graph baseGraph,
                                            java.lang.Object source,
                                            org.eclipse.core.runtime.IProgressMonitor monitor)

Description copied from interface: IGraphRegistry

Registers a given Graph. This method is usually called directly after a Graph has been loaded, to announce it to the global registry. If the base Graph is not a memory graph, an implementation may create a delegating CachingGraph and use this instead of the base Graph. This is done in the default implementation - the new graph is then returned.

Specified by:

register in interface IGraphRegistry

Parameters:

baseURI - the base URI to register the new graph under

baseGraph - the base "raw" Graph

source - the source where the graph has been loaded from

monitor - an optional progress monitor (if caches are built up)

Returns:

either baseGraph or a CachingGraph that wraps it

removeListener

public void removeListener(IGraphRegistryListener listener)

Specified by:

removeListener in interface IGraphRegistry

replaceBaseURI

public void replaceBaseURI(java.net.URI oldURI,
                           java.net.URI newURI)

Specified by:

replaceBaseURI in interface IGraphRegistry

setDirty

public void setDirty(com.hp.hpl.jena.graph.Graph graph,
                     boolean value)

Specified by:

setDirty in interface IGraphRegistry

setSource

public void setSource(java.net.URI baseURI,
                      java.lang.Object source)

Specified by:

unregister

public void unregister(java.net.URI baseURI)

Specified by:
