抽象工厂模式(abstract factory pattern) 详解

本文地址: http://blog.csdn.net/caroline_wendy/article/details/27091671

参考工厂模式: http://blog.csdn.net/caroline_wendy/article/details/27081511

抽象工厂模式: 提供一个接口, 用于创建相关或依赖对象的家族, 而不需要明确指定具体类.

全部代码: http://download.csdn.net/detail/u012515223/7403553

具体方法:

1. 提供一个抽象工厂(abstract factory)接口(interface)类, 不同的具体工厂(concrete factory)继承此类.

代码:

/**
 * @time 2014年5月26日
 */
package factory;

/**
 * @author C.L.Wang
 *
 */
public interface PizzaIngredientFactory {
	public Dough createDough();
	public Sauce createSauce();
	public Cheese createCheese();
	public Veggies[] createVeggies();
	public Pepperoni createPepperoni();
	public Clams createClam();
}

代码:

/**
 * @time 2014年5月26日
 */
package factory;

/**
 * @author C.L.Wang
 *
 */
public class NYPizzaIngredientFactory implements PizzaIngredientFactory {

	/* (non-Javadoc)
	 * @see factory.PizzaIngredientFactory#createDough()
	 */
	@Override
	public Dough createDough() {
		// TODO Auto-generated method stub
		return new ThinCrustDough();
	}

	/* (non-Javadoc)

	@Override
	public Sauce createSauce() {
		// TODO Auto-generated method stub

	@Override

	@Override

	}
