<?php

namespace App\Product\Repository;

use Batenburg\CacheBundle\Repository\Contract\CacheRepositoryInterface;
use App\Product\Model\Brand;
use App\Product\Repository\Contract\BrandRepositoryInterface;

class BrandCacheRepository implements BrandRepositoryInterface
{

    const EXPIRES_AFTER_IN_SECONDS = 3600;

    /**
     * @var CacheRepositoryInterface
     */
    private $cacheRepository;

    /**
     * @var BrandRepositoryInterface
     */
    private $brandRepository;

    /**
     * @param CacheRepositoryInterface $cacheRepository
     * @param BrandRepositoryInterface $brandRepository
     */
    public function __construct(CacheRepositoryInterface $cacheRepository, BrandRepositoryInterface $brandRepository)
    {
        $this->cacheRepository = $cacheRepository;
        $this->brandRepository = $brandRepository;
    }

    /**
     * @param int $id
     * @return Brand|null
     */
    public function findById(int $id): ?Brand
    {
        $item = $this->cacheRepository->rememberItem(
            "brands.{$id}",
            [$this->brandRepository, 'findById'],
            self::EXPIRES_AFTER_IN_SECONDS,
            $id
        );

        return $item->get();
    }

    /**
     * @return Brand[]
     */
    public function findAll(): array
    {
        $item = $this->cacheRepository->rememberItem(
            "brands.all",
            [$this->brandRepository, 'findAll'],
            self::EXPIRES_AFTER_IN_SECONDS
        );

        return $item->get();
    }
}
