isReadOnly

public boolean isReadOnly()

Description copied from interface: ArtifactRepository

Checks if the repository should be treated as read-only. If true is returned, all modification operations such as adding or removing artifacts should fail with a StorageException.

Specified by:

isReadOnly in interface ArtifactRepository

Returns:

true when the repository is read-only, false otherwise.

setReadOnly

public void setReadOnly(boolean readOnly)

disconnect

public void disconnect()

Description copied from interface: ArtifactRepository

Disconnects the repository.

Specified by:

disconnect in interface ArtifactRepository

getStorage

public RDFStorage getStorage()

getIriDecoder

public IRIDecoder getIriDecoder()

Description copied from interface: ArtifactRepository

Gets an IRI encoder / decoder usable with this repository.

Specified by:

getIriDecoder in interface ArtifactRepository

Returns:

getIriFactory

public IRIFactory getIriFactory()

Gets the IRI factory used for creating the IRIs when building a RDF graph.

setIriFactory

public void setIriFactory(IRIFactory iriFactory)

Configures the IRI factory used for creating the IRIs when building a RDF graph.

Parameters:

iriFactory -

init

public void init()

Checks the repository status and initializes the metadata when necessary

isInitialized

public boolean isInitialized()

Checks whether the storage has been initialized - it seems to contain the appropriate metadata

Returns:

true when the repository is ready to use

initMetadata

public boolean initMetadata()

Initializes the repository metadata using the default OWL resource files.

Returns:

true when the repository was initialized sucessfully.

clearMetadata

public void clearMetadata()

getArtifactIRIs

public Collection<org.eclipse.rdf4j.model.IRI> getArtifactIRIs()
                                                        throws StorageException

Description copied from interface: ArtifactRepository

Obtains a list of all artifact IRIs in the repository.

Specified by:

getArtifactIRIs in interface ArtifactRepository

Returns:

The list of all artifacts.

Throws:

StorageException

getArtifactIRIs

public Collection<org.eclipse.rdf4j.model.IRI> getArtifactIRIs(org.eclipse.rdf4j.model.IRI pageIri)

Parameters:

pageIri - the source page IRI

Returns:

the list of artifact IRIs

Throws:

StorageException
