toperatordao.java

这是我在东方标准学习的时候做的一个项目

package dao.product;

import java.util.List;

import bean.TOperator;

public interface TOperatorDAO {

	/*
	 * this method verify whether the login is successfull
	 * return
	 *   common.Constant.ERROR
	 *   common.Constant.ADMIN
	 *   common.Constant.OPERATOR
	 */
	public int verifyOperator(String operator_id, String operator_pwd);

	public boolean add(TOperator operator);

	public boolean delete(String id);

	public boolean update(TOperator operator);

	public TOperator findByID(String id);

	public List findAll();

}
