> Can anyone explain the relationship between swap! and reset! ? swap! is for "CAS"
See: http://en.wikipedia.org/wiki/Compare-and-swap In the examples here, you're fully replacing a value, so reset! is fine... assuming that the replacement value was not derived from the existing value. If the atom was deref-ed (via deref or the @ reader macro), that value is a perception of a potentially old state. Making a decision outside of an atomic swap operation would potentially be invalidated by another thread performing a conflicting mutation. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
