Public Variables and Functions


-?>

Usage: (-?> x form)
       (-?> x form & forms)

Same as clojure.core/-> but returns nil as soon as the threaded value is nil itself (thus short-circuiting any pending computation).
Examples :
(-?> "foo" .toUpperCase (.substring 1)) returns "OO"
(-?> nil .toUpperCase (.substring 1)) returns nil

.?.
