salesforce-将请求跳转到标准组件的页面

// Add an existing customer
    public PageReference add() {
    	
    	Retargeting_BMS_CN__c newTarget = new Retargeting_BMS_CN__c();
    	
    	newTarget.Active_BMS_CN__c = true;
    	newTarget.BU_BMS_CN__c = strBU;    	
    	 
        insert newTarget;
		
	// Redirect to edit page of added customer
	Schema.DescribeSObjectResult sObjResult = Retargeting_BMS_CN__c.sObjectType.getDescribe();//标准写法我也不懂。
	PageReference newPage = new ApexPages.StandardController(newTarget).edit();//newTarget是自己定义好的，各个属性都赋值好了，会将所有信息发送到edit页面中
	newPage.setRedirect(true);
	return newPage;
    }

该方法的standardcontroller是Retargeting_BMS_CN__c，
