    • setTransactionSettings

      public void setTransactionSettings(TransactionSetting... settings)
      Description copied from interface: SailConnection
      Pass any transaction-specific settings to the SailConnection. This method needs to be called before the transaction is started .

      Sail implementations can override this method to receive the transaction settings (to inspect and/or pass them along to any wrapped sail objects). Remember to call super.setTransactionSettings(settings) if you override this method.

      Specified by:
      setTransactionSettings in interface SailConnection
      Overrides:
      setTransactionSettings in class SailConnectionWrapper
      Parameters:
      settings - the transaction settings on which the next transaction operates. It may or may not contain the isolation level.

    • begin

      public void begin() throws SailException
      Description copied from interface: SailConnection
      Begins a transaction requiring SailConnection.commit() or SailConnection.rollback() to be called to close the transaction. The transaction will use the default IsolationLevel level for the SAIL, as returned by Sail.getDefaultIsolationLevel().
      Specified by:
      begin in interface SailConnection
      Overrides:
      begin in class SailConnectionWrapper
      Throws:
      SailException - If the connection could not start a transaction or if a transaction is already active on this connection.

      Description copied from interface: SailConnection
      Begins a transaction with the specified IsolationLevel level, requiring SailConnection.commit() or SailConnection.rollback() to be called to close the transaction.
      Specified by:
      begin in interface SailConnection
      Overrides:
      begin in class SailConnectionWrapper
      Parameters:
      level - the transaction isolation level on which this transaction operates.
      Throws:
      SailException - If the connection could not start a transaction, if the supplied transaction isolation level is not supported, or if a transaction is already active on this connection.

      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface SailConnection

    • prepare

      public void prepare() throws SailException
      Description copied from interface: SailConnection
      Checks for an error state in the active transaction that would force the transaction to be rolled back. This is an optional call; calling or not calling this method should have no effect on the outcome of SailConnection.commit() or SailConnection.rollback(). A call to this method must be followed by (in the same thread) with a call to SailConnection.prepare() , SailConnection.commit(), SailConnection.rollback(), or SailConnection.close() . This method may be called multiple times within the same transaction by the same thread. If this method returns normally, the caller can reasonably expect that a subsequent call to SailConnection.commit() will also return normally. If this method returns with an exception the caller should treat the exception as if it came from a call to SailConnection.commit().
      Specified by:
      prepare in interface SailConnection
      Overrides:
      prepare in class SailConnectionWrapper
      Throws:
      SailException - If there is an active transaction and it cannot be committed.

      Specified by:
      statementAdded in interface SailConnectionListener
      Parameters:

    • statementRemoved

      public void statementRemoved(Statement statement)
      Description copied from interface: SailConnectionListener

      Specified by:
      statementRemoved in interface SailConnectionListener
      Parameters:

      Description copied from interface: SailConnection
      Gets all statements from the specified contexts that have a specific subject, predicate and/or object. All three parameters may be null to indicate wildcards. The includeInferred parameter can be used to control which statements are fetched: all statements or only the statements that have been added explicitly.

      contexts - The context(s) to get the data from. Note that this parameter is a vararg and as such is optional. If no contexts are specified the method operates on the entire repository. A null value can be used to match context-less statements.
      Returns:
      The statements matching the specified pattern.
      Throws:
      SailException - If the Sail object encountered an error or unexpected situation internally.

      Returns:
      true iff the store contains any statements matching the supplied criteria, false otherwise.
      Throws:
      SailException - If the Sail object encountered an error or unexpected situation internally.
