<?php

namespace RemiSan\Serializer\NameExtractor\Event;

use League\Event\EventInterface;
use RemiSan\Serializer\SerializableClassNameExtractor;

class EventNameExtractor implements SerializableClassNameExtractor
{
    /**
     * @param  string $class
     * @return string
     */
    public function extractName($class)
    {
        if (! $this->canExtractName($class)) {
            throw new \InvalidArgumentException();
        }

        return $class::NAME;
    }

    /**
     * @param  string $class
     * @return bool
     */
    public function canExtractName($class)
    {
        return is_subclass_of($class, EventInterface::class) && defined($class::NAME);

Due to PHP Bug #53727, is_subclass_of might return inconsistent results on some PHP versions if \League\Event\EventInterface::class can be an interface. If so, you could instead use ReflectionClass::implementsInterface.
