## Custom processors

[Processors](../src/Processors) implement the various steps involved in converting annotations into an OpenAPI spec.

Writing a custom processor is the recommended way to extend swagger-php in a clean way.

Processors are expected to implement the `__invoke()` method expecting the current `Analysis` object as single parameter:

```php
<?php
...
use OpenApi\Analysis;
...

class MyCustomProcessor
{
    public function __invoke(Analysis $analysis)
    {
        // custom processing    
    }
}
``` 

* **schema-query-parameter processor**

  A processor that takes a vendor tag (expecting a schema `#ref`) and injects all properties of that given schema as
  query parameter to the [request definition](processors/schema-query-parameter/app/ProductController.php).

  [source](processors/schema-query-parameter)

* **sort-components processor**

  A processor that sorts components so they appear in alphabetical order.
