Usage Finder

The UsageFinderInterface is the interface for components that aim to find usages of resources.

But you should be more interested in the SupportsUsageFinderInterface, which combined with UsageFinder allow to have multiple usage finder at once.

Example :

<?php

use Yokai\SafeDelete\Usage\Finder\UsageFinder;
use Yokai\SafeDelete\Usage\Finder\SupportsUsageFinderInterface;

$descriptor = new UsageFinder([
    new class implements SupportsUsageFinderInterface {/* ... */},
    new class implements SupportsUsageFinderInterface {/* ... */},
    /* ... */
]);

echo $descriptor->count($object); // any positive integer
echo $descriptor->find($object); // list of usages (possibly empty)

integration this library is shipped with adapters for doctrine/orm
