LazyCombiner
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.
Type parameters
- Buff
-
the type of the buffers that contain leaf results and this combiner chains together
- Elem
-
the type of the elements in the combiner
- To
-
the type of the collection the combiner produces

Concrete methods
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

Value parameters

Attributes
- Returns
-
the parallel builder containing both the elements of this and the
other
builder
