    • 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
        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.

      • getAdditionalHttpHeaders

        public Map<String,​String> getAdditionalHttpHeaders()
        Get the additional HTTP headers which will be used
        Returns:
        a read-only view of the additional HTTP headers which will be included in every request to the server.

      • setAdditionalHttpHeaders

        public void setAdditionalHttpHeaders​(Map<String,​String> additionalHttpHeaders)
        Set additional HTTP headers to be included in every request to the server, which may be required for certain unusual server configurations. This will only take effect on connections subsequently returned by getConnection().
        Parameters:
        additionalHttpHeaders - a map containing pairs of header names and values. May be null

      • getHttpClient

        public final org.apache.http.client.HttpClient getHttpClient()
        Description copied from interface: HttpClientDependent
        HttpClient that has been assigned or has been used by this object. The life cycle might not be or might be tied to this object, depending on whether HttpClient was passed to or created by this object respectively.
        Specified by:
        getHttpClient in interface HttpClientDependent
        Returns:
        an HttpClient instance or null

      • setHttpClient

        public void setHttpClient​(org.apache.http.client.HttpClient httpClient)
        Description copied from interface: HttpClientDependent
        Assign an HttpClient that this object should use. The life cycle of the given HttpClient is independent of this object. Closing or shutting down this object does not have any impact on the given client. Callers must ensure that the given client is properly closed elsewhere.
        Specified by:
        setHttpClient in interface HttpClientDependent

      • 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.

      • 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.

      • 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

      • setPreferredTupleQueryResultFormat

        public void setPreferredTupleQueryResultFormat​(TupleQueryResultFormat format)
        Sets the preferred serialization format for tuple query results to the supplied TupleQueryResultFormat, overriding the SPARQLProtocolSession 's default preference. Setting this parameter is not necessary in most cases as the SPARQLProtocolSession by default indicates a preference for the most compact and efficient format available.
        Parameters:
        format - the preferred TupleQueryResultFormat. If set to 'null' no explicit preference will be stated.

      • getPreferredTupleQueryResultFormat

        public TupleQueryResultFormat getPreferredTupleQueryResultFormat()
        Indicates the current preferred TupleQueryResultFormat.
        Returns:
        The preferred format, of 'null' if no explicit preference is defined.

      • setPreferredRDFFormat

        public void setPreferredRDFFormat​(RDFFormat format)
        Sets the preferred serialization format for RDF to the supplied RDFFormat, overriding the SPARQLProtocolSession's default preference. Setting this parameter is not necessary in most cases as the SPARQLProtocolSession by default indicates a preference for the most compact and efficient format available.

        Use with caution: if set to a format that does not support context serialization any context info contained in the query result will be lost.

        Parameters:
        format - the preferred RDFFormat. If set to 'null' no explicit preference will be stated.

      • getPreferredRDFFormat

        public RDFFormat getPreferredRDFFormat()
        Indicates the current preferred RDFFormat.
        Returns:
        The preferred format, of 'null' if no explicit preference is defined.

      • setUsernameAndPassword

        public void setUsernameAndPassword​(String username,
                                   String password)
        Set the username and password to use for authenticating with the remote repository.
        Parameters:
        username - the username. Setting this to null will disable authentication.
        password - the password. Setting this to null will disable authentication.

      • getRepositoryURL

        public String getRepositoryURL()
