README

Little testing repositories enhancer.

This project aims to provide quick and easy filtering capabilities to everzet/persisted-objects.

Usage

You just need to decorate the testing repository with carlosV2\Funnel\Funnel. For example:

use carlosV2\Funnel\Funnel;
use Everzet\PersistedObjects\Repository;

class MyTestingRepository
{
    /**
     * @var Funnel
     */
    private $repository;
    
    /**
     * @param Repository $repository
     */
    public function __construct(Repository $repository)
    {
        $this->repository = new Funnel($repository);
    }
    
    // ...
}

Funnel also implements Everzet\PersistedObjects\Repository so you don't lose any feature and yet you gain some more instead:

• findAll(): Returns an array with all the objects. This is an alias for getAll.
• findBy(callable): Returns an array with all the matching objects. Empty array is returned if none is found.
• findOneBy(callable): Returns the first matching object or null if none is found.
• countBy(callable): Returns an integer representing the number of matching objects.

For example:

$objects = $funnel->findBy(function ($object) {
    return $object->getData() === 'foo';
});

In addition, Funnel provides some generic filters that can be used to speed up development:

• AllOfFilter
• AnyOfFilter
• MethodFilter
• MethodsFilter
• PropertyFilter
• PropertiesFilter
• TypeFilter
• BeingFilter
• HavingFilter

Those filters can be used by composing a new method applying the following rule (where "Not" is optional):

   find |
findOne > + By + [Not] + Filter
  count |

For example:

• findByProperty(...): Finds all the objects that have the given property and value.
• findOneByMethod(...): Finds the first object that matches the given method and value.
• countByNotType(...): Counts all the objects that don't have the given type.

If none of the provided filters match your requirements, you can also add your own filters to Funnel to make them available when composing new methods.

Feel free to create a pull request with your own generic filters! :)

Alternatively, you can decorate an array in order to provide the Funnel API on top of it. For example:

$myArray = [$obj1, $obj2, $obj3];

// Any Funnel-compatible method can be used here
Funnel($myArray)->countByType(\DateTime::class);
