Hydrator not passing instance to filters on extract

Questions Components & MVC

Noticed that for most hydration implementations on the extract method the filtering happens only by property name or method name without passing an instance object, which in fact is a filter method optional second argument while still not passed in most implementations.
Now my concern is if that is a bug or if there is another reason behind it I simply don’t see.

Welcome to the Laminas community,

can you show us a reproducable code example? That would make things much more clearer.
Thanks in advance. :wink:

Sure @ezkimo here you go - minimum reproducible code

<?php
declare(strict_types=1);

use Laminas\Hydrator\ReflectionHydrator;

require __DIR__ . '/vendor/autoload.php';

class Foo {
    protected DateTimeImmutable $ts;
}
$foo = new Foo();
$hydrator = new ReflectionHydrator();
$hydrator->addFilter('uninitialized', function (string $property, mixed $instance): bool {
    assert($instance instanceof Foo);
    return true;
});
$extracted = $hydrator->extract($foo);

The explanation can be found in the related release notes:

This argument’s primary use case is with anonymous objects, to facilitate reflection; the ClassMethodsHydrator , for instance, was updated to pass the $instance value only when an anonymous object is detected.

If you think this will be useful for more than anonymous objects, then please create a feature request and describe your use case. Thanks in advance! :+1:t3:
