Method Detail

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

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

getBaseURI

public static java.lang.String getBaseURI(org.eclipse.core.resources.IFile rdfaFile)
                                   throws java.io.IOException

Throws:

java.io.IOException

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

getURLString

public static java.lang.String getURLString(org.eclipse.core.resources.IFile rdfaFile)
                                     throws java.io.IOException

Throws:

java.io.IOException

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

isTidy

public static boolean isTidy(org.eclipse.core.resources.IFile rdfaFile)
                      throws java.io.IOException

Throws:

java.io.IOException

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

load

public static com.hp.hpl.jena.graph.Graph load(java.lang.String urlString,
                                               java.lang.String baseURI,
                                               boolean tidy)
                                        throws java.net.MalformedURLException,
                                               java.io.IOException

Throws:

java.net.MalformedURLException

java.io.IOException

load

public static com.hp.hpl.jena.graph.Graph load(java.lang.String urlString,
                                               java.lang.String baseURI,
                                               boolean tidy,
                                               org.eclipse.core.resources.IFile baseFile)
                                        throws java.net.MalformedURLException,
                                               java.io.IOException

                 com.hp.hpl.jena.graph.Graph graph,
                 java.lang.String baseURI)
          throws java.io.IOException

Throws:
