# Promise Completion Source

Promise manageable from outer scope, similar to C#'s TaskCompletionSource

## Synopsis

```typescript

class PromiseSource {

    get promise(): Promise;

    get resolved(): boolean;

    get rejected(): boolean;

    get completed(): boolean;

    constructor(timeout?: number);

    reject(reason?: any): void;

    resolve(value?: TResult): void;

}

```

## Example

```typescript

import PromiseSource from "promise-cs";

function doSomething(): Promise

{

	let ps = new PromiseSource(/* optional timeout in millisecond */);

	// Some async action, event or something

	someAsyncAction((err, result) => {

		if (err) {

			ps.reject(err);

			return;

		}

		

		ps.resolve(result);

	});

	return ps.promise;

}

doSomething()

	.then(num => console.log(num))

	.catch(reason => console.error(reason))

;

```
