  17. def combine[N <: T, NewTo >: ParArray[T]](other: Combiner[N, NewTo]): Combiner[N, NewTo]

    Combines the contents of the receiver builder and the other builder, producing a new builder containing both their elements.

    Combines the contents of the receiver builder and the other builder, producing a new builder containing both their elements.

    This method may combine the two builders by copying them into a larger collection, by producing a lazy view that gets evaluated once result is invoked, or use a merge operation specific to the data structure in question.

    Note that both the receiver builder and other builder become invalidated after the invocation of this method, and should be cleared (see clear) if they are to be used again.

    Also, combining two combiners c1 and c2 for which c1 eq c2 is true, that is, they are the same objects in memory:

    c1.combine(c2)

    always does nothing and returns c1.

    N

    the type of elements contained by the other builder

    NewTo

    the type of collection produced by the other builder

    other

    the other builder

    returns

    the parallel builder containing both the elements of this and the other builder

    Gives a hint how many elements are expected to be added when the next result is called. Some builder classes will optimize their representation based on the hint.

    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.
