Hi folks
It may seem silly question but why when I doseq over a vector that is
wrapped in an atom and change the vector using swap! while I am inside
doseq, the doseq sets to the beginning of the vector intermittently:
(def a-data (atom [15 9 8 1 4 11 7 12 13 14 5 3 16 2 10 6]))
(defn switch-two-elements [the-vector] ... ) ;; swaping two elements in
given vector
(doseq [element @a-data]
(println @a-data) (println element)
(swap! a-data switch-two-elements))
[15 9 8 1 4 11 7 12 13 14 5 3 16 2 10 6]
15
[1 9 8 15 4 11 7 12 13 14 5 3 16 2 10 6]
9
[1 4 8 15 9 11 7 12 13 14 5 3 16 2 10 6]
8
[1 4 5 15 9 11 7 12 13 14 8 3 16 2 10 6]
1 ==> I expect this to be 15
I suspect the reason would be the same as the one behind not changing a
collection in java while iterating over it.
I appreciate any insight on this.
Thanks a lot
Best regards
