Package io.vavr.concurrent

This package contains basic building blocks for creating fast, asynchronous, non-blocking parallel code.

A io.vavr.concurrent.Future represents an asynchronous task. It is a placeholder for a value that becomes available at some point. With the help of Future we efficiently perform many non-blocking operations in parallel. The value of a Future is supplied concurrently and can subsequently be used. Multiple concurrent tasks represented by Futures can be composed to a single Future.

Interface Summary

Modifier and TypeInterface and Description
public interface
Future<
Type of the computation result.
T>

A Future is a computation result that becomes available at some point.

public interface
Promise<
The result type of the underlying Future.
T>

A Promise is a write-once wrapper around a read-only Future which can complete the underlying Future with a value or an exception.
