在传统的抽象工厂中,工厂通常创建同类型的产品,而Abstract Factory with heterogenous components则允许工厂创建不同类型的产品。这意味着工厂需要能够生产不同类型的产品,并且需要在一起工作以创建相互协调的产品系列。
下面是一个示例的解决方法,其中定义了一个接口,工厂和具体产品实现类,以创建来自同一家公司的heterogeneous components(异构组件)。
//组件接口
interface Component {}
//具体组件类
class ConcreteComponentA implements Component {}
class ConcreteComponentB implements Component {}
class ConcreteComponentC implements Component {}
//工厂接口
interface Factory {
Component createComponent();
}
//具体工厂类
class ConcreteFactoryA implements Factory {
Component createComponent() {
return new ConcreteComponentA();
}
}
class ConcreteFactoryB implements Factory {
Component createComponent() {
return new ConcreteComponentB();
}
}
class ConcreteFactoryC implements Factory {
Component createComponent() {
return new ConcreteComponentC();
}
}
//客户端使用
class Client {
private Component component;
private Factory factory;
public Client(Factory factory) {
this.factory = factory;
this.component = factory.createComponent();
}
public void doSomething() {
//使用component做些什么
}
}
//示例使用
public static void main(String[] args) {
Factory factoryA = new ConcreteFactoryA();
Factory factoryB = new ConcreteFactoryB();
Factory factoryC = new ConcreteFactoryC();
Client clientA = new Client(factoryA);
Client clientB = new Client(factoryB);
Client clientC = new Client(factoryC);
clientA.doSomething();
clientB.doSomething();
clientC.doSomething();
}
该示例中,具体组件类 ConcreteComponentA、 ConcreteComponentB和 ConcreteComponentC 实现了 Component 接口, 这意味着它们都是同一类型的异构组件。
然后定义了一个工
