Asyncc.java

High-quality port of async.js to Java.
Primarily for use with Vert.x.
Uses async primitives (error-first callbacks), for performance and genericism.

Adds nice structure to callback-passing-style codebases.

Complete Documentation:

https://async-java.github.io/org/ores/async/Asyncc.html#method.summary

Installation with Maven

Simple example:

import org.ores.async.Asyncc;

public void retrieveValue(){
  Asyncc.Parallel(t -> t.done(null,"foo"), (err, results) -> {
    
    
  });  
}

Utility Methods

Links to the documentation

Control Flow

• Series
• Parallel/ParallelLimit
• Waterfall
• Inject - (most recommended)

Map/Filter/Reduce/Each

• Map, MapSeries, MapLimit
• Filter, FilterSeries, FilterLimit
• Reduce / ReduceRight
• Each, EachSeries, EachLimit

Queue / Priority Queue

• Queue
• PriorityQueue

Locking

• Basic async locking

(Because the synchronized keyword blocks).

Improvements and Quality

This library improves upon async.js. For those familiar, this library makes these improvements:

1. Composability. This is available because Java has method overloading and JS doesn't.

In JS:

With Java:

2. async.waterfall is considered harmful. We use a ma

3. We have a shortCircuited boolean available to check if we can end early.
