def initialize: (*_Each[Elem] enums) -> void

Generates a new enumerator object that iterates over the elements of given enumerable objects in sequence.

e = Enumerator::Chain.new(1..3, [4, 5])
e.to_a #=> [1, 2, 3, 4, 5]
e.size #=> 5

Public Instance Methods

def each: () { (Elem) -> void } -> self
          | () -> Enumerator[Elem, self]

Iterates over the elements of the first enumerable by calling the “each” method on it with the given arguments, then proceeds to the following enumerables in sequence until all of the enumerables are exhausted.

If no block is given, returns an enumerator.
