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

Combines the contents of the receiver builder and the
otherbuilder, producing a new builder containing both their elements.Combines the contents of the receiver builder and the
otherbuilder, 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
resultis invoked, or use a merge operation specific to the data structure in question.Note that both the receiver builder and
otherbuilder become invalidated after the invocation of this method, and should be cleared (seeclear) if they are to be used again.Also, combining two combiners
c1andc2for whichc1 eq c2istrue, 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
otherbuilder- NewTo
the type of collection produced by the
otherbuilder- other
the other builder
- returns
the parallel builder containing both the elements of this and the
otherbuilder
