  - ### 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.
      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 `RepositoryConnection`s.
      Returns:
        A connection that allows operations on this repository.
      Throws:
        `RepositoryException` - If something went wrong during the creation of the Connection.
