      • getAllowWrite

        public boolean getAllowWrite()
        Description copied from interface: TransactionService
        Determine if the repository has been put into read only mode. This is independent of the current user.
        Specified by:
        getAllowWrite in interface TransactionService
        Returns:
        true if the repository is allowed to perform write operations

      • isReadOnly

        public boolean isReadOnly()
        Description copied from interface: TransactionService
        Determine if ALL user transactions will be read-only. The 'System' user is always allowed to write.
        Specified by:
        isReadOnly in interface TransactionService
        Returns:
        Returns true if all transactions are read-only AND the current user is not the 'System' user.

      • getUserTransaction

        public javax.transaction.UserTransaction getUserTransaction()
        Description copied from interface: TransactionService
        Gets a user transaction that supports transaction propagation. This is like the EJB REQUIRED transaction attribute.
        Specified by:
        getUserTransaction in interface TransactionService
        Returns:
        the user transaction

      • getUserTransaction

        public javax.transaction.UserTransaction getUserTransaction​(boolean readOnly)
        Description copied from interface: TransactionService
        Gets a user transaction that supports transaction propagation. This is like the EJB REQUIRED transaction attribute.
        Specified by:
        getUserTransaction in interface TransactionService
        Parameters:
        readOnly - Set true for a READONLY transaction instance, false otherwise. Note that it is not always possible to force a write transaction if the system is in read-only mode.
        Returns:
        the user transaction

      • getUserTransaction

        public javax.transaction.UserTransaction getUserTransaction​(boolean readOnly,
                                                            boolean ignoreSystemReadOnly)
        Description copied from interface: TransactionService
        Gets a user transaction that supports transaction propagation. This is like the EJB REQUIRED transaction attribute.
        Specified by:
        getUserTransaction in interface TransactionService
        Parameters:
        readOnly - Set true for a READONLY transaction instance, false otherwise.
        ignoreSystemReadOnly - true to force the read-only flag to be respected regardless of the system read-only mode.
        Returns:
        the user transaction

      • getNonPropagatingUserTransaction

        public javax.transaction.UserTransaction getNonPropagatingUserTransaction()
        Description copied from interface: TransactionService
        Gets a user transaction that ensures a new transaction is created. Any enclosing transaction is not propagated. This is like the EJB REQUIRES_NEW transaction attribute - when the transaction is started, the current transaction will be suspended and a new one started.
        Specified by:
        getNonPropagatingUserTransaction in interface TransactionService
        Returns:
        Returns a non-propagating user transaction

      • getNonPropagatingUserTransaction

        public javax.transaction.UserTransaction getNonPropagatingUserTransaction​(boolean readOnly)
        Description copied from interface: TransactionService
        Gets a user transaction that ensures a new transaction is created. Any enclosing transaction is not propagated. This is like the EJB REQUIRES_NEW transaction attribute - when the transaction is started, the current transaction will be suspended and a new one started.
        Specified by:
        getNonPropagatingUserTransaction in interface TransactionService
        Parameters:
        readOnly - Set true for a READONLY transaction instance, false otherwise. Note that it is not always possible to force a write transaction if the system is in read-only mode.
        Returns:
        Returns a non-propagating user transaction

      • getNonPropagatingUserTransaction

        public javax.transaction.UserTransaction getNonPropagatingUserTransaction​(boolean readOnly,
                                                                          boolean ignoreSystemReadOnly)
        Description copied from interface: TransactionService
        Gets a user transaction that ensures a new transaction is created. Any enclosing transaction is not propagated. This is like the EJB REQUIRES_NEW transaction attribute - when the transaction is started, the current transaction will be suspended and a new one started.
        Specified by:
        getNonPropagatingUserTransaction in interface TransactionService
        Parameters:
        readOnly - Set true for a READONLY transaction instance, false otherwise.
        ignoreSystemReadOnly - true to force the read-only flag to be respected regardless of the system read-only mode.
        Returns:
        Returns a non-propagating user transaction
