Package javascalautils

Contains various utility classes translated from the Scala language.

See: Description

Interface Summary

Interface	Description
Either<L,R>	Represents a value of one of two possible types.
Option<T>	Represents optional values.
ThrowableFunction0<T>	A function that takes no arguments and returns a value of type T.
Try<T>	The Try type represents a computation that may either result in an exception, or return a successfully computed value.

Class Summary

Class	Description
EitherCompanion	Acts as a Scala type companion object for Left/Right.
Failure<T>	Represents the failure implementation of Try.
Left<L,R>	Represents the Left side of an Either.
LeftProjection<L,R>	This is a left-biased wrapper for an instance of Either.
None<T>	Represents an empty Option.
OptionCompanion	Acts as a Scala type companion object for Option/Some/None.
Right<L,R>	Represents the Right side of an Either.
RightProjection<L,R>	This is a right-biased wrapper for an instance of Either.
Some<T>	Represents an Option holding a value.
Success<T>	Represents the successful implementation of Try.
TryCompanion	Acts as a Scala type companion object for Try/Success/Failure.
Validator	Used internally to validate parameters

Package javascalautils Description

Contains various utility classes translated from the Scala language.
The following three types are all what is known as container types.
They represent various use cases, such as containing one or zero value (Option), one of two values (Either) and value or exception (Try) The aim with these utility classes is to provide neat and concise programming patterns.

• Option/Some/None
• Try/Success/Failure
• Either/Left/Right

It is possible to make transitions between the container types.
This image below aims to illustrate the transitions that can be made and where they lead.
