I have rewrite catalog product resource collection MagentoCatalogModelResourceModelProductCollection.

Class override successfully but functions override is not working.

Suppose, i want overrider setOrder()function. But it does not works . Always calling Core function instead of rewrite class function

Class

<?php
namespace AmitBeraCoreRewriteModelRewriteCatalogResourceModelProduct;

class Collection extends MagentoCatalogModelResourceModelProductCollection


 protected $appState;
 public function __construct(
 MagentoFrameworkDataCollectionEntityFactory $entityFactory,
 PsrLogLoggerInterface $logger,
 MagentoFrameworkDataCollectionDbFetchStrategyInterface $fetchStrategy,
 MagentoFrameworkEventManagerInterface $eventManager,
 MagentoEavModelConfig $eavConfig,
 MagentoFrameworkAppResourceConnection $resource,
 MagentoEavModelEntityFactory $eavEntityFactory,
 MagentoCatalogModelResourceModelHelper $resourceHelper,
 MagentoFrameworkValidatorUniversalFactory $universalFactory,
 MagentoStoreModelStoreManagerInterface $storeManager,
 MagentoFrameworkModuleManager $moduleManager,
 MagentoCatalogModelIndexerProductFlatState $catalogProductFlatState,
 MagentoFrameworkAppConfigScopeConfigInterface $scopeConfig,
 MagentoCatalogModelProductOptionFactory $productOptionFactory,
 MagentoCatalogModelResourceModelUrl $catalogUrl,
 MagentoFrameworkStdlibDateTimeTimezoneInterface $localeDate,
 MagentoCustomerModelSession $customerSession,
 MagentoFrameworkStdlibDateTime $dateTime,
 MagentoFrameworkAppState $appState,
 MagentoCustomerApiGroupManagementInterface $groupManagement,
 MagentoFrameworkDBAdapterAdapterInterface $connection = null
 ) 
 parent::__construct(
 $entityFactory,
 $logger,
 $fetchStrategy,
 $eventManager,
 $eavConfig,
 $resource,
 $eavEntityFactory,
 $resourceHelper,
 $universalFactory,
 $storeManager,
 $moduleManager,
 $catalogProductFlatState,
 $scopeConfig,
 $productOptionFactory,
 $catalogUrl,
 $localeDate,
 $customerSession,
 $dateTime,
 $groupManagement,
 $connection
 );
 $this->_appState = $appState;

 
 public function setOrder($attribute, $dir = MagentoFrameworkDBSelect::SQL_DESC)
 
 echo __METHOD__;
 exit;
 if ($attribute == 'price') 
 $this->addAttributeToSort($attribute, $dir);
 else 
 parent::setOrder($attribute, $dir);
 
 return $this;

 <preference for="MagentoCatalogModelResourceModelProductCollection" 
 type="AmitBeraCoreRewriteModelRewriteCatalogResourceModelProductCollection" />
</config> 

Whenever use

$objectManager = MagentoFrameworkAppObjectManager::getInstance();
/** @var MagentoCatalogModelResourceModelProductCollection $productCollection */
$productCollection = $objectManager->create('MagentoCatalogModelResourceModelProductCollection');
echo get_class($productCollection );

result:

AmitBeraCoreRewriteModelRewriteCatalogResourceModelProductCollectionInterceptor

Question:

• i donot understand why i am not able to override function
  setorder()


• Why echo get_class($productCollection ); give Interceptor class

If you overwriting
MagentoCatalogModelResourceModelProductCollection, just traverse this folder location, you will find the file and folder with same name i.e Collection. So its points to folder location collection.

If you want to do some function with sorting overwrite MagentoCatalogModelResourceModelProductCollectionProductLimitation or using plugin concept to set $productLimitationFilters
