public final class LeftAll<L,R>
extends Object
implements SemigroupFactory<Semigroup<L>,Either<L,R>>

A Semigroup instance formed by Either<L,R> and a semigroup over L. The application to two Either values is right-biased, such that for a given Either x and y:

• if x is a Right value, the result is x
• if y is a Right value, the result is y
• if both x and y are left values, the result is the application of the x and y values in terms of the provided semigroup, wrapped in Either.left(L)

For the Monoid, see LeftAll.
