Option<RT> |
filter(java.util.function.Predicate<? super RT> test)
Keep only elements for which the supplied predicates hold
e.g.

filter(java.util.function.Predicate<? super RT> test,
java.util.function.Function<? super RT,? extends L> rightToLeft) |

<LT1> Either<LT1,RT> |
flatMapLeft(java.util.function.Function<? super L,? extends Either<LT1,RT>> mapper)
Perform a flatMap operation on the Left type
|
Either<L,RT> |
flatMapLeftToRight(java.util.function.Function<? super L,? extends Either<L,RT>> fn)
A flatMap operation that keeps the Left and Right types the same
|
<R> R |
fold(java.util.function.Function<? super L,? extends R> left,
java.util.function.Function<? super RT,? extends R> right)
Visitor pattern for this Ior.

map(java.util.function.Function<? super RT,? extends R> fn)
Transform this functor using the supplied transformation function
|
<R> Either<R,RT> |
mapLeft(java.util.function.Function<? super L,? extends R> fn)
Always transform the Left type of this Either if it is present using the provided transformation function
|
Either<L,RT> |
mapLeftToRight(java.util.function.Function<? super L,? extends RT> fn)
If this Either contains the Left type, transform it's value so that it contains the Right type
|
java.lang.String |
mkString()
Returns the class name and the name of the subclass, if there is any value, the value is showed between square brackets.
|
Either<L,RT> |
peek(java.util.function.Consumer<? super RT> action)
Peek at the current value of this Transformable, without transforming it
|
Either<L,RT> |
peekLeft(java.util.function.Consumer<? super L> action)
Peek at the Left type value if present
|
