Either
The control package contains an implementation of the io.vavr.control.Either control which is either Left or Right. A given Either is projected to a Left or a Right. Both cases can be further processed with control operations map, flatMap, filter. If a Right is projected to a Left, the Left control operations have no effect on the Right value. If a Left is projected to a Right, the Right control operations have no effect on the Left value.
Option
The Option control is a replacement for java.util.Optional. An Option is either
io.vavr.control.Option.Some value or io.vavr.control.Option.None.
In contrast to Optional, Option supports null values, i.e. it is possible to call new Some(null).
However, Option.of(null) results in None.
Try
Exceptions are handled with the io.vavr.control.Try control which is either a io.vavr.control.Try.Success, containing a result, or a io.vavr.control.Try.Failure, containing an Exception.
| Modifier and Type | Interface and Description |
|---|---|
| public interface | Either<
The type of the Left value of an Either. L, The type of the Right value of an Either. R>Either represents a value of two possible types. |
| public interface | HashCodes
Deprecated
Will be removed from public API
Utility that allows to compute hashcodes without var-arg conversion into arrays for common
types of vavr.
