29. #### def sizeHint(coll: TraversableLike[_, _], delta: Int): Unit

    Gives a hint that one expects the `result` of this builder to have the same size as the given collection, plus some delta.

    Gives a hint that one expects the `result` of this builder to have the same size as the given collection, plus some delta. This will provide a hint only if the collection is known to have a cheap `size` method. Currently this is assumed to be the case if and only if the collection is of type `IndexedSeqLike`. Some builder classes will optimize their representation based on the hint. However, builder implementations are still required to work correctly even if the hint is wrong, i.e. a different number of elements is added.

    coll

      the collection which serves as a hint for the result's size.

    delta

      a correction to add to the `coll.size` to produce the size hint.

    size

      the hint how many elements will be added.
