abstract class LazyBuilder[Elem, +To] extends Builder[Elem, To]

A builder that constructs its result lazily. Iterators or iterables to be added to this builder with ++= are not evaluated until result is called.

Elem

To

type of the collection this builder builds.

  28. 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.
