    • Method Detail

      • setBaseSail

        public void setBaseSail​(Sail baseSail)
        Description copied from interface: StackableSail
        Sets the base Sail that this Sail will work on top of. This method will be called before the initialize() method is called.
        Specified by:
        setBaseSail in interface StackableSail
      • verifyBaseSailSet

        protected void verifyBaseSailSet()
      • setDataDir

        public void setDataDir​(File dataDir)
        Description copied from interface: Sail
        Sets the data directory for the Sail. The Sail can use this directory for storage of data, parameters, etc. This directory must be set before the Sail is initialized.
        Specified by:
        setDataDir in interface Sail
      • init

        public void init()
                  throws SailException
        Description copied from interface: Sail
        Initializes the Sail. Care should be taken that required initialization parameters have been set before this method is called. Please consult the specific Sail implementation for information about the relevant parameters.
        Specified by:
        init in interface Sail
        Throws:
        SailException - If the Sail could not be initialized.
      • shutDown

        public void shutDown()
                      throws SailException
        Description copied from interface: Sail
        Shuts down the Sail, giving it the opportunity to synchronize any stale data. Care should be taken that all initialized Sails are being shut down before an application exits to avoid potential loss of data. Once shut down, a Sail can no longer be used until it is re-initialized.
        Specified by:
        shutDown in interface Sail
        Throws:
        SailException - If the Sail object encountered an error or unexpected situation internally.
      • isWritable

        public boolean isWritable()
                           throws SailException
        Description copied from interface: Sail
        Checks whether this Sail object is writable, i.e. if the data contained in this Sail object can be changed.
        Specified by:
        isWritable in interface Sail
        Throws:
        SailException
      • getConnection

        public SailConnection getConnection()
                                     throws SailException
        Description copied from interface: Sail
        Opens a connection on the Sail which can be used to query and update data. Depending on how the implementation handles concurrent access, a call to this method might block when there is another open connection on this Sail.
        Specified by:
        getConnection in interface Sail
        Throws:
        SailException - If no transaction could be started, for example because the Sail is not writable.
      • getValueFactory

        public ValueFactory getValueFactory()
        Description copied from interface: Sail
        Gets a ValueFactory object that can be used to create IRI-, blank node-, literal- and statement objects.
        Specified by:
        getValueFactory in interface Sail
        Returns:
        a ValueFactory object for this Sail object.
      • getSupportedIsolationLevels

        public List<IsolationLevel> getSupportedIsolationLevels()
        Description copied from interface: Sail
        Retrieve the IsolationLevels supported by this SAIL, ordered by increasing complexity.
        Specified by:
        getSupportedIsolationLevels in interface Sail
        Returns:
        a non-empty List of supported Isolation Levels, in order of increasing complexity. Every SAIL supports at least one IsolationLevel.
      • getCollectionFactory

        public Supplier<CollectionFactory> getCollectionFactory()
        Description copied from interface: Sail
        Gets a CollectionFactory that may be optimized for this store and may or may not use disk or other resources.
        Specified by:
        getCollectionFactory in interface Sail
        Returns:
        a CollectionFactory
