Re: [basex-talk] file:read-text-lines performance

I can see there is a list with the deterministic functions in the specs [1] but not so sure about the BaseX specific functions. Is it possible to know if a function is deterministic or not?

You can have a look into the appropriate Java class, and check for functions tagged with NDT:

If we have some more time, we might include this information in our Wiki.

I tried file:read-text-lines("/path.txt") is file:read-text-lines("/path.txt") but it doesn't work.

The "is" operator operates only on nodes.
