      • beginTransaction

        Session beginTransaction()
                  throws ClientException
        Opens a new transaction scoped to this Session if one is not already active. A Session that has an active transaction will perform all sends and all delivery dispositions under that active transaction. If the user wishes to send with the same session but outside of a transaction they user must commit the active transaction and not request that a new one be started. A session can only have one active transaction at a time and as such any call to begin while there is a currently active transaction will throw an ClientTransactionNotActiveException to indicate that the operation being requested is not valid at that time. This is a blocking method that will return successfully only after a new transaction has been started.
        Returns:
        this Session instance.
        Throws:
        ClientException - if an error occurs while attempting to begin a new transaction.

      • commitTransaction

        Session commitTransaction()
                   throws ClientException
        Commit the currently active transaction in this Session. Commit the currently active transaction in this Session but does not start a new transaction automatically. If there is no current transaction this method will throw an ClientTransactionNotActiveException to indicate this error. If the active transaction has entered an in doubt state or was remotely rolled back this method will throw an error to indicate that the commit failed and that a new transaction need to be started by the user. When a transaction rolled back error occurs the user should assume that all work performed under that transaction has failed and will need to be attempted under a new transaction. This is a blocking method that will return successfully only after the current transaction has been committed.
        Returns:
        this Session instance.
        Throws:
        ClientException - if an error occurs while attempting to commit the current transaction.

      • rollbackTransaction

        Session rollbackTransaction()
                     throws ClientException
        Roll back the currently active transaction in this Session. Roll back the currently active transaction in this Session but does not automatically start a new transaction. If there is no current transaction this method will throw an ClientTransactionNotActiveException to indicate this error. If the active transaction has entered an in doubt state or was remotely rolled back this method will throw an error to indicate that the roll back failed and that a new transaction need to be started by the user.
        Returns:
        this Session instance.
        Throws:
        ClientException - if an error occurs while attempting to roll back the current transaction.
