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.

Type parameters

N

the type of elements contained by the other builder

NewTo

the type of collection produced by the other builder

Value parameters

other

the other builder

Attributes

Returns

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