public final class Collapse<_1,_2>
extends Object
implements BiSemigroupFactory<Semigroup<_1>,Semigroup<_2>,Tuple2<_1,_2>>

A Semigroup instance formed by a Tuple2<_1, _2> and semigroups over _1 and _2. Successively collapses multiple Tuple2s into a single Tuple2 by collapsing the values of each slot under the provided semigroup instance.

For the Monoid, see Collapse.
