Hi, I'm sure this has been discussed to death but I can't figure it out.
I've got a file-seq sequence from (file-seq (java.io.File. "/DirectoryWithMillionsOfFiles/")) that will cause an out of memory error if realized. I want to call a function such as println on every element in the sequence. I understand that naming the sequence will cause it to be realized. The problems 1. I can't use map as in (map println (file-seq (java.io.File. "/DirectoryWithMillionsOfFiles"))). Map realizes the sequence. 2. I can't use for as in (for [x (files)] (println x)). For realizes the sequence. 3. I can't use dorun because even though dorun doesn't realize the sequence, it can't execute a function on every element. 4. I can't use loop recur because it also realizes the sequence: (loop [a (files) b (first a)] (println b) (recur (rest a) (first a))) 5. I can't use refs because even though they provide state, they can't save the state of the sequence without realizing the sequence. My question *Should I try the new stream library?* * * Thank you for your time. -Sean -- You received this message because you are subscribed to the Google Groups "Clojure" group.
