Package org.eclipse.rdf4j.federated.repository

Class FedXRepositoryWrapper

java.lang.Object

org.eclipse.rdf4j.repository.base.RepositoryWrapper

org.eclipse.rdf4j.federated.repository.FedXRepositoryWrapper

All Implemented Interfaces:

FederatedServiceResolverClient, DelegatingRepository, Repository, RepositoryResolverClient

public class FedXRepositoryWrapper
extends RepositoryWrapper
implements RepositoryResolverClient, FederatedServiceResolverClient

Wrapper for the FedXRepository in order to allow for lazy initialization.

The wrapper is used from FedXRepositoryFactory in environments with a RepositoryManager, e.g. in the RDF4J workbench. The background is that the RDF4J repository manager requires control over the repository instance.

The data directory and the RepositoryResolver are handled by RDF4J RepositoryManager.

FedXRepositoryWrapper

public FedXRepositoryWrapper(FedXRepositoryConfig fedXConfig)

Method Detail

setDataDir

public void setDataDir(File dataDir)

Description copied from interface: Repository

Set the directory where data and logging for this repository is stored.

Specified by:

setDataDir in interface Repository

Overrides:

setDataDir in class RepositoryWrapper

Parameters:

dataDir - the directory where data for this repository is stored

getDataDir

public File getDataDir()

Description copied from interface: Repository

Get the directory where data and logging for this repository is stored.

Specified by:

getDataDir in interface Repository

Overrides:

getDataDir in class RepositoryWrapper

Returns:

the directory where data for this repository is stored.

isInitialized

public boolean isInitialized()

Description copied from interface: Repository

Indicates if the Repository has been initialized. Note that the initialization status may change if the Repository is shut down.

Specified by:

isInitialized in interface Repository

Overrides:

isInitialized in class RepositoryWrapper

Returns:

true iff the repository has been initialized.

init

public void init()
          throws RepositoryException

Description copied from interface: Repository

Initializes this repository. A repository needs to be initialized before it can be used, however explicitly calling this method is not necessary: the repository will automatically initialize itself if an operation is executed on it that requires it to be initialized.

Specified by:

init in interface Repository

Overrides:

init in class RepositoryWrapper

Throws:

RepositoryException - If the initialization failed.

createFactory

protected FedXFactory createFactory()

Create the initialized FedXFactory

Returns:

shutDown

public void shutDown()
              throws RepositoryException

Description copied from interface: Repository

Shuts the repository down, releasing any resources that it keeps hold of. Once shut down, the repository can no longer be used until it is re-initialized.

Specified by:

shutDown in interface Repository

Overrides:

shutDown in class RepositoryWrapper

Throws:

RepositoryException

setRepositoryResolver

public void setRepositoryResolver(RepositoryResolver resolver)

Specified by:

setRepositoryResolver in interface RepositoryResolverClient

setFederatedServiceResolver

public void setFederatedServiceResolver(FederatedServiceResolver resolver)

Description copied from interface: FederatedServiceResolverClient

Sets the FederatedServiceResolver to use for this client.

Specified by:

setFederatedServiceResolver in interface FederatedServiceResolverClient

Parameters:

resolver - The resolver to use.
