trait LazyCombiner[Elem, +To, Buff <: Growable[Elem] with Sizing] extends Combiner[Elem, To]

Implements combining contents of two combiners by postponing the operation until result method is called. It chains the leaf results together instead of evaluating the actual collection.

Elem

the type of the elements in the combiner

To

the type of the collection the combiner produces

Buff

the type of the buffers that contain leaf results and this combiner chains together

    Returns true if this combiner has a thread-safe += and is meant to be shared across several threads constructing the collection.

    By default, this method returns false.

  12. def combine[N <: Elem, NewTo >: To](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
