DefaultArtifactRepository

public DefaultArtifactRepository()

Method Detail

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.

getArtifactIRIs

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

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.

getArtifactInfo

public Collection<Artifact> getArtifactInfo()

Description copied from interface: ArtifactRepository

Obtains the basic information about the artifacts. Note that the resulting objects are not necessarily the complete artifacts. Use ArtifactRepository.getArtifact(IRI) to load the complete artifacts of the appropriate types.

Specified by:

getArtifactInfo in interface ArtifactRepository

Returns:

A collection of objects that represent the available artifacts.

getArtifact

public Artifact getArtifact(org.eclipse.rdf4j.model.IRI artifactIri)

Description copied from interface: ArtifactRepository

Obtains an artifact from the repository.

Specified by:

getArtifact in interface ArtifactRepository

Parameters:

artifactIri - the artifact IRI

Returns:

the artifact or null when there is no such artifact available

addArtifact

public void addArtifact(Artifact artifact)

Description copied from interface: ArtifactRepository

Adds an artifact to the repository. If the artifact IRI is null a new IRI is generated using ArtifactRepository.createArtifactIri(Artifact).

Specified by:

addArtifact in interface ArtifactRepository

Parameters:

artifact - the artifact to add

createArtifactIri

public org.eclipse.rdf4j.model.IRI createArtifactIri(Artifact artifact)

Description copied from interface: ArtifactRepository

Generates a unique IRI for a new artifact based on the strategy of the given repository.

Specified by:

createArtifactIri in interface ArtifactRepository

Parameters:

artifact - the artifact to generate to IRI for

Returns:

The generated IRI

replaceArtifact

public void replaceArtifact(org.eclipse.rdf4j.model.IRI artifactIri,
                            Artifact artifact)

Description copied from interface: ArtifactRepository

Sets an IRI to a artifact and stores it into the repository while replacing the eventual existing artifact with that IRI.

Specified by:

replaceArtifact in interface ArtifactRepository

Parameters:

artifactIri - the target IRI

artifact - the artifact to store

removeArtifact

public void removeArtifact(org.eclipse.rdf4j.model.IRI artifactIri)

Description copied from interface: ArtifactRepository

Removes an artifact and all its derived artifacts from the repository.

Specified by:

removeArtifact in interface ArtifactRepository

Parameters:

artifactIri - the artifact IRI

clear

public void clear()

Description copied from interface: ArtifactRepository

getIriDecoder

public IRIDecoder getIriDecoder()

Description copied from interface: ArtifactRepository

Specified by:

getIriDecoder in interface ArtifactRepository

Returns:

disconnect

public void disconnect()

Description copied from interface: ArtifactRepository

Disconnects the repository.

Specified by:

disconnect in interface ArtifactRepository
