Uses of Either in javascalautils

Classes in javascalautils that implement Either

Modifier and Type	Class and Description
class	Left<L,R> Represents the Left side of an Either.
class	Right<L,R> Represents the Right side of an Either.

Methods in javascalautils that return Either

Modifier and Type	Method and Description
<T> Either<T,R>	LeftProjection.flatMap(java.util.function.Function<L,Left<T,R>> function) If this projection contains a Left then a new Left is returned containing the value from the original Right mapped via the provided function, else the contained Either is returned as is.
<T> Either<L,T>	RightProjection.flatMap(java.util.function.Function<R,Right<L,T>> function) If this projection contains a Right then a new Right is returned containing the value from the original Right mapped via the provided function, else the contained Either is returned as is.
<T> Either<T,R>	LeftProjection.map(java.util.function.Function<L,T> function) If this projection contains a Left then a new Left is returned containing the value from the original Right mapped via the provided function, else the contained Either is returned as is.
<T> Either<L,T>	RightProjection.map(java.util.function.Function<R,T> function) If this projection contains a Right then a new Right is returned containing the value from the original Right mapped via the provided function, else the contained Either is returned as is.
Either<R,L>	Right.swap() Returns a Left containing the value for this instance.
Either<R,L>	Either.swap() If this is a Left, then return the left value in Right or vice versa.
Either<R,L>	Left.swap() Returns a Right containing the value for this instance.

Methods in javascalautils that return types with arguments of type Either

Modifier and Type	Method and Description
Option<Either<L,R>>	LeftProjection.filter(java.util.function.Predicate<L> predicate) Returns a Some wrapping the Either if it's a Left and the value of the Left matches the predicate, else None .
Option<Either<L,R>>	RightProjection.filter(java.util.function.Predicate<R> predicate) Returns a Some wrapping the Either if it's a Right and the value of the Right matches the predicate, else None .
