This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Enumerator.feed (from ruby core) --- e.feed obj -> nil --- Sets the value to be returned by the next yield inside `e`. If the value is not set, the yield returns nil. This value is cleared after being yielded. # Array#map passes the array's elements to "yield" and collects the # results of "yield" as an array. # Following example shows that "next" returns the passed elements and # values passed to "feed" are collected as an array which can be # obtained by StopIteration#result. e = [1,2,3].map p e.next #=> 1 e.feed "a" p e.next #=> 2 e.feed "b" p e.next #=> 3 e.feed "c" begin e.next rescue StopIteration p $!.result #=> ["a", "b", "c"] end o = Object.new def o.each x = yield # (2) blocks p x # (5) => "foo" x = yield # (6) blocks p x # (8) => nil x = yield # (9) blocks p x # not reached w/o another e.next end e = o.to_enum e.next # (1) e.feed "foo" # (3) e.next # (4) e.next # (7) # (10)
