In such a way as to do something

You may, for example, be assigned to read a textbook, and because perhaps the first chapter of this one is dull, you might infer that all the rest of the book will likewise be dull. Of course, the rest of a book is often even worse than its beginning. Yet it could be that the rest of the books would prove exciting were it read with an open mind. The problem here is that you run the risk of judging an entire text in such a way as to preclude any other possibilities.

I have seen "such as to do something", but I haven't seen the structure "in such a way as to do something."
So, I'd like to know what role "as" in "in such a way as to do something" plays.
Thank you in advance for your help.
