Method rollback

sdk-python/src/graphlite_sdk/transaction.py:149–174

Rollback the transaction Discards all changes made within this transaction. This is called automatically when the transaction context exits, so explicit rollback is rarely needed. Raises: TransactionError: If rollback fails Examples:

(self)

            raise TransactionError(f"Failed to commit: {e}")

    def rollback(self) -> None:
        """
