オブジェクトの生成

Overloads:

  • #initialize(parent, range, count_limit = nil) ⇒ Enumerator

    Parameters:

  • #initialize(parent, first, direction, count_limit) ⇒ Enumerator

    Parameters:

    • first (When::TM::TemporalPosition) —

      始点

    • direction (Symbol) —

      :forward - 昇順, :reverse - 降順

    • count_limit (Integer) —

      繰り返し回数(デフォルトは指定なし)
