  • Constructor Details

    • RepositoryWrapper

      public RepositoryWrapper()
      Creates a new RepositoryWrapper.

    • RepositoryWrapper

      public RepositoryWrapper(Repository delegate)
      Creates a new RepositoryWrapper and calls setDelegate(Repository) with the supplied delegate repository.

  • Method Details

    • setDelegate

      public void setDelegate(Repository delegate)
      Specified by:
      setDelegate in interface DelegatingRepository

    • getDelegate

      public Repository getDelegate()
      Specified by:
      getDelegate in interface DelegatingRepository

    • 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
      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
      Returns:
      the directory where data for this repository is stored.

    • 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
      Throws:
      RepositoryException

    • 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.
      Specified by:
      isWritable in interface Repository
      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.

      Specified by:
      getConnection in interface Repository
      Returns:
      A connection that allows operations on this repository.
      Throws:
      RepositoryException - If something went wrong during the creation of the Connection.

    • getValueFactory

      public ValueFactory getValueFactory()
      Description copied from interface: Repository
      Gets a ValueFactory for this Repository.
      Specified by:
      getValueFactory in interface Repository
      Returns:
      A repository-specific ValueFactory.

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • 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
      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
      Throws:
      RepositoryException - If the initialization failed.
