Class Discovery

There are many situations where a component may need to parse a list of classes for attributes, getting this list of classes can be done using the class discovery component.

Scan Directory Class Discovery

The scan directory class discovery component allows you to define paths to directories and returns a list of classes found in those directories.

<?php

use ForestCityLabs\Framework\Utility\ClassDiscovery\ScanDirectoryDiscovery;

$discovery = new ScanDirectoryDiscovery([__DIR__ . '/src/Entity']);
$classes = $discovery->discoverClasses();

The above example will return all classes defined in the src/Entity directory.

Manual Class Discovery

The simplest way to define classes is to just tell the system which classes you are looking for.

<?php

use ForestCityLabs\Framework\Utility\ClassDiscovery\ManualDiscovery;

$discovery = new ManualDiscovery([\DateTimeInterface::class]);
$classes = $discover->discoverClasses();

Chained Class Discovery

The above methods can be combined using the chained class discovery method.

<?php

use ForestCityLabs\Framework\Utility\ClassDiscovery\ChainedDiscovery;
use ForestCityLabs\Framework\Utility\ClassDiscovery\ScanDirectoryDiscovery;
use ForestCityLabs\Framework\Utility\ClassDiscovery\ManualDiscovery;

$discovery = new ChainedDiscovery([
    new ManualDiscovery([\DateTimeInterface::class]),
    new ScanDirectoryDiscovery([__DIR__ . 'src/Entity']),
]);
$classes = $discovery->discoverClasses();
