数组赋值的问题

public function setParm($parameter, $value) {		$this->parameter[$parameter] = $value;		return $this;	}function geturl($type){     $this->setproductparm($type);     return $this->getData();     }     private function setproductparm($urltype){     $this->parameter=array();     $this->type="";     $this->setParm("Marketplace",self::marketplaceId);     $this->version="2009-01-01";     switch ($urltype){        case "RequestReport":                $this->setParm("Action","RequestReport");            $this->setParm("ReportType","_GET_MERCHANT_LISTINGS_DATA_");        break;        case "GetReportList":              $this->setParm("Action","GetReportList");               $this->setParm("ReportRequestIdList.Id.1",$this->ReportRequestId);        break;        case "GetReport":              $this->setParm("Action","GetReport");               $this->setParm("ReportId",$this->ReportId);          break;                                   }             }

//看看是不是下面的方法哪里处理了getData();
