public final class LeftAny<L,R>
extends java.lang.Object
implements MonoidFactory<Monoid<L>,Either<L,R>>

A Monoid instance formed by Either<L,R> and a monoid over L. The application to two Either values is left-biased, such that for a given Either x and 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 monoid, wrapped in Either.left(L)
• if only x is a left value, the result is x
• if only y is a left value, the result is y
• if neither x nor y are left values, the result is y

For the Semigroup, see LeftAny.
