  • put (v: V_, k: K_)
    Change some existing entry or add the new one.
  • fast_put (v: V_, k: K_)

  • add (v: V_, k: K_)
    To add a new entry k with its associated value v.
  • remove (k: K_)
    Remove entry k (which may exist or not before this call).
  • fast_remove (k: K_)
    Same job as remove, but uses basic = for comparison.
  • clear_count
    Discard all items (is_empty is True after that call).
  • clear_count_and_capacity
    Discard all items (is_empty is True after that call).
