 * already stored if otherwise we will select products and store in cache.
 */
public function listProducts($table, $resultType, $order, $limit)
{
	// Instantiating the service
	$serviceCache = $this->getServiceLocator()->get('jvcache-cache');
	
	// set a variable $cacheSuccess how false
	$cacheSuccess = false;
	
	// Caching Products requests not to do so in the Bank
	if ($serviceCache->status) {
	    $resultCache = $serviceCache->cache->getItem('findAllProdutosIndex', $cacheSuccess);
	    
	    if ($cacheSuccess) {
	        $result = unserialize($resultCache);
	    }
	}
	
	if (!$cacheSuccess) {
	    $result = $this->findAll($table, $resultType, $order, $limit);
	
	    // if the status is true then generates the cache file
	    if ($factoryCache->status) {
	        $resultCache = serialize($result);
	        $serviceCache->cache->addItem('findAllProdutosIndex', $resultCache);
