Waitable
========

[](#waitable)

The Waitable class is used for asynchronous computing. A Waitable object has three states

- Fulfilled
- Rejected
- Running: `This is the default state when it's created`

This class is analogue to JavaScript Promise class

Installation
============

[](#installation)

You can install this library from Composer executing the following commands `composer require srdestino/waitable` then all you have to do is use this as in the following examples

Usage
=====

[](#usage)

Create a new Waitable
---------------------

[](#create-a-new-waitable)

```
$waitable = new Waitable(function (IWaitable $waitable){
  LongTask();
  $waitable->Resolve(null); // When you call this method it will mark the Waitable as Fulfilled
});
```

This will create a new Waitable and the function we pass to the constructor will be executed asynchronously

Wait until the Waitable is resolved
-----------------------------------

[](#wait-until-the-waitable-is-resolved)

```
$waitable = new Waitable(function (IWaitable $waitable){
  $waitable->Resolve("Test"); // When you call this method it will mark the waitable as Fulfilled
});

$result = $waitable->Wait();
echo $result; // It will print "Test"
```

Wait until all waitables are resolved
-------------------------------------

[](#wait-until-all-waitables-are-resolved)

```
$firstWaitable = new Waitable(function (IWaitable $waitable){
    $waitable->Resolve("First value");
});
$secondWaitable = new Waitable(function (IWaitable $waitable) use($secondValue){
    $waitable->Resolve("Second value");
});
list($firstResult, $secondResult) = Waitable::WaitAll([$firstWaitable, $secondWaitable]);

echo $firstResult; // "First value"
echo $secondResult; // "Second value"
```

The static method WaitAll receives an array of IWaitable and wait until all are fulfilled. This method will return an array with the values returned by all the waitables.
