Method Details

setDataDir

public void setDataDir(File dataDir)

Description copied from interface: Repository

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

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.

Returns:

the directory where data for this repository is stored.

isWritable

public boolean isWritable()
                   throws RepositoryException

Description copied from interface: Repository

Checks whether this repository is writable, i.e. if the data contained in this repository can be changed. The writability of the repository is determined by the writability of the Sail that this repository operates on.

Throws:

RepositoryException

getValueFactory

public ValueFactory getValueFactory()

Description copied from interface: Repository

Gets a ValueFactory for this Repository.

Returns:

A repository-specific ValueFactory.

initializeInternal

protected void initializeInternal()
                           throws RepositoryException

Specified by:

initializeInternal in class AbstractRepository

Throws:

RepositoryException

shutDownInternal

protected void shutDownInternal()
                         throws RepositoryException

Specified by:

shutDownInternal in class AbstractRepository

Throws:

RepositoryException

getConnection

public RepositoryConnection getConnection()
                                   throws RepositoryException

Description copied from interface: Repository

Opens a connection to this repository that can be used for querying and updating the contents of the repository. Created connections need to be closed to make sure that any resources they keep hold of are released. The best way to do this is to use a try-with-resources block, as follows:

 try (RepositoryConnection conn = repository.getConnection()) {
        // perform operations on the connection
 }
 

Note that RepositoryConnection is not guaranteed to be thread-safe! The recommended pattern for repository access in a multi-threaded application is to share the Repository object between threads, but have each thread create and use its own RepositoryConnections.

Returns:

A connection that allows operations on this repository.

Throws:

RepositoryException - If something went wrong during the creation of the Connection.
