enum.cycle(n=nil) { |obj| block } â nil
enum.cycle(n=nil) â an_enumerator
enum.cycle(n=nil) â an_enumerator
Instance Public methods
Calls block for each element of enum repeatedly
n times or forever if none or nil is given. If a
non-positive number is given or the collection is empty, does nothing.
Returns nil if the loop has finished without getting
interrupted.
#cycle saves elements in an internal array so changes to enum after the first pass have no effect.
If no block is given, an enumerator is returned instead.
1 2 3 | a = ["a", "b", "c"]a.cycle { |x| puts x } # print, a, b, c, a, b, c,.. forever.a.cycle(2) { |x| puts x } # print, a, b, c, a, b, c. |
