promises
========

[](#promises)

Promises in PHP using **pthreads v1.0.0+**

Promise Manager
===============

[](#promise-manager)

The Promise Manager represents a pool of threads used to fulfill promises in parallel.

The only public API for the `PromiseManager` is the constructor:

```
public PromiseManager::__construct($size = 4, $worker = \Worker::class, $ctor = [])

```

See `Pool::__construct` in the PHP manual.

Promise
=======

[](#promise)

A `Promise` represents a promise to execute the public interface of a `Promisable` at some time in the future:

```
public Promise::__construct(PromiseManager $manager, Promisable $promisable)

```

A `Promise` provides the ability to schedule the subsequent execution of the public interface of a `Thenable`.

```
public Promise Promise::then(Thenable $then)

```

Interfaces
==========

[](#interfaces)

IPromisable

```
public void IPromisable::onFulfill();

```

IThenable

```
public void IThenable::onFulfilled(Promisable $promised);
public void IThenable::onError(Promisable $promised);

```

Notes
=====

[](#notes)

Exceptions thrown by `Promisable`, or `Thenable` objects will be caught and bubble up to invoke subsequent `Thenable::onError`.

```
$manager = new PromiseManager();
$promise =
	new Promise($manager, new CalculateTheMeaningOfLife());
$promise
	->then(
		new AddTwo($promise))
	->then(
		new PrintMeaning($promise));

$manager->shutdown();
```

This is a work in progress
--------------------------

[](#this-is-a-work-in-progress)

Note that, this is a work in progress, that does not aim for maximum compatibility with any established standard but rather an easy to use implementation, that is compatible with and takes full advantage of pthreads.

While reading the API, remember everything you read other than `PromiseManager` is a *pthreads* object
