Usage

ApiDoc() annotation

The bundle provides an ApiDoc() annotation for your controllers:

<?php

namespace Your\Namespace;

class YourController extends Controller
{
    /**
     * @ApiDoc(
     *  resource="true",
     *  description="This is a description of your API method",
     *  filters={
     *      {"name"="a-filter", "dataType"="integer"},
     *      {"name"="another-filter", "dataType"="string", "pattern"="(foo|bar) ASC|DESC"}
     *  }
     * )
     */
    public function getAction()
    {
    }

    /**
     * @ApiDoc(
     *  description="Create a new Object",
     *  formType="Your\Namespace\Form\Type\YourType"
     * )
     */
    public function postAction()
    {
    }
}

The following parameters are recognized:

• resource: whether the method describes a resource or not;

• description: a description of the API method;

• filters: an array of filters;

• formType: the Form Type associated to the method, useful for POST|PUT methods.

Each filter has to define a name parameter, but other parameters are free.

If you set a formType, then the bundle automatically extracts parameters based on the given type, and determines for each parameter its data type, and if it's required or not.
