Install via composer
--------------------

[](#install-via-composer)

```
$ composer require b2pweb/bdf-pipeline
```

Usage Instructions
------------------

[](#usage-instructions)

A basic and classic use of pipeline with a pipe processor.

```
use Bdf\Pipeline\Pipeline;
use Bdf\Pipeline\CallableFactory\LinkedCallableFactory;

$pipeline = new Pipeline(new LinkedCallableFactory());
$pipeline->pipe(function($value) {
    return $value + 2;
});

// Returns 12
$pipeline->send(10);
```

The pipeline lib comes with an advanced processor (used by default).

```
use Bdf\Pipeline\Pipeline;
use Bdf\Pipeline\CallableFactory\StackCallableFactory;

$pipeline = new Pipeline(new StackCallableFactory());
$pipeline->pipe(function($next, $foo, $bar) {
    // Do something
    ...

    $result = $next($foo, $bar);

    // Do something else
    ...

    return $result;
});
$pipeline->outlet(function($foo, $bar) {
    return "${foo}.${bar}";
});
// Manage multiple parameters
echo $pipeline->send('foo', 'bar'); // Print foo.bar
```

Ok, So ?
--------

[](#ok-so-)

You can use this package as a classic pipe, but it was designed to be easily extended:

```
$pipeline->pipe(new LogCommand());
$pipeline->outlet(new CreateUserHandler());

...

$pipeline->prepend(new TransactionnalCommand());
$pipeline->send(new CreateUserCommand());
```

```
class TransactionnalCommand
{
    public function __invoke($next, $command)
    {
        try {
            $result = $next($command);

            // Commit and return the result
            ...
            return $result;
        } catch (\Throwable $exception) {
            // Rollback and propagate exception
            throw $exception;
        }
    }
}
```

The pipeline is reusable:

```
$pipeline = new Pipeline();
$pipeline->pipe(new Double());

$new = clone $pipeline;

$new->pipe(new Double());

echo $pipeline->send(2); // 4
echo $new->send(2); // 8
```
