Method Detail

addExistingPrefixes

public static void addExistingPrefixes(java.io.File file,
                                       java.util.Properties properties)
                                throws java.io.IOException

Throws:

java.io.IOException

addPrefixesToProperties

public static void addPrefixesToProperties(java.util.Properties properties,
                                           com.hp.hpl.jena.shared.PrefixMapping pm)

close

public void close(org.eclipse.core.resources.IFile file)
           throws java.lang.Exception

Description copied from interface: IGraphStore

Closes any resources allocated by a given file.

Parameters:

file - the file representing the store

Throws:

java.lang.Exception

createConnection

public static com.franz.ag.AllegroGraphConnection createConnection(java.util.Properties properties)
                                                            throws java.lang.Exception

Throws:

java.lang.Exception

createGraph

public static com.franz.ag.AllegroGraphJenaImpl createGraph(com.franz.ag.AllegroGraph ag,
                                                            java.util.Properties properties)

getBaseURI

public java.net.URI getBaseURI(org.eclipse.core.resources.IFile file,
                               java.util.Set imports)
                        throws java.lang.Exception

Description copied from interface: IGraphStore

Gets the declared base URI and the owl:imports of a given file. For example, in the standard file back-end this would use file introspection to check the declared xml:base and the owl:imports of the owl:Ontology.

Parameters:

file - the file to get the base URI of

imports - an initially empty Set that will contain imported URIs

Returns:

the base URI

Throws:

java.lang.Exception

getImageMetadata

public ImageMetadata getImageMetadata()

Description copied from interface: IGraphStore

Gets a (base) image to display files of this type in the Navigator (and potentially elsewhere).

Returns:

the IImage or null to use the default image

initPrefixMapping

public static void initPrefixMapping(com.hp.hpl.jena.graph.Graph graph,
                                     java.util.Properties p)

isReadOnly

public boolean isReadOnly(org.eclipse.core.resources.IFile file)

Description copied from interface: IGraphStore

Checks if a given IFile is read-only. This is typically used for graph stores that just provide a view on some external data source, such as a D2RQ database (here: all files would be read-only), or for stores like the Sesame remote back-end where selected files may be read-only.

Returns:

true if this is a read-only store

load

public com.hp.hpl.jena.graph.Graph load(org.eclipse.core.resources.IFile file,
                                        org.eclipse.core.runtime.IProgressMonitor monitor)
                                 throws java.lang.Exception

Description copied from interface: IGraphStore

Creates a new Jena Graph for a given IFile. This method is only called after the system has determined whether this engine is actually responsible for the file's extension.

Parameters:

file - the file to load

monitor - the monitor for status reports or null

Returns:

a new Graph

Throws:

java.lang.Exception - if something went wrong

save

public void save(org.eclipse.core.resources.IFile file,
                 com.hp.hpl.jena.graph.Graph graph,
                 java.lang.String baseURI)
          throws java.io.IOException

Throws:

java.io.IOException

saveAs

public boolean saveAs(org.eclipse.core.resources.IFile file,
                      com.hp.hpl.jena.graph.Graph graph,
                      java.lang.String baseURI)
               throws java.lang.Exception

Returns:

true if the new IFile shall be the editor's input

Throws:

java.lang.Exception

updateNamespaceProperties

public static void updateNamespaceProperties(com.hp.hpl.jena.graph.Graph graph,
                                             java.lang.String baseURI,
                                             java.util.Properties properties)
