图-访问者模式结构图
Visitor : 为该对象结构中 ConcreteElement 的每一个类声明一个 Visit 操作。
abstract class Visitor { public abstract void VisitConcreteElementA(ConcreteElementA elementA); public abstract void VisitConcreteElementB(ConcreteElementB elementB); }
ConcreteVisitor : 实现每个由 Visitor 声明的操作。每个操作实现算法的一部分,而该算法片段乃是对应于结构中对象的类。
class ConcreteVisitor1 extends Visitor { @Override public void VisitConcreteElementA(ConcreteElementA elementA) { System.out.println(this.getClass().getName() + " 访问 " + elementA.getClass().getName()); } @Override public void VisitConcreteElementB(ConcreteElementB elementB) { System.out.println(this.getClass().getName() + " 访问 " + elementB.getClass().getName()); } } class ConcreteVisitor2 extends Visitor { @Override public void VisitConcreteElementA(ConcreteElementA elementA) { System.out.println(this.getClass().getName() + " 访问 " + elementA.getClass().getName()); } @Override public void VisitConcreteElementB(ConcreteElementB elementB) { System.out.println(this.getClass().getName() + " 访问 " + elementB.getClass().getName()); } }
Element : 定义一个Accpet操作,它以一个访问者为参数。
abstract class Element { public abstract void Accept(Visitor visitor); }
ConcreteElement : 实现 Element 声明的 Accept 操作。
class ConcreteElementA extends Element { @Override public void Accept(Visitor visitor) { visitor.VisitConcreteElementA(this); } } class ConcreteElementB extends Element { @Override public void Accept(Visitor visitor) { visitor.VisitConcreteElementB(this); } }
ObjectStructure : 可以枚举它的元素,可以提供一个高层的接口以允许访问者访问它的元素。
class ObjectStructure { private List<Element> elements = new ArrayList<Element>(); public void Attach(Element element) { elements.add(element); } public void Detach(Element element) { elements.remove(element); } public void Accept(Visitor visitor) { for (Element elem : elements) { elem.Accept(visitor); } } }
测试代码
public class VisitorPattern {
public static void main(String[] args) {
ObjectStructure o = new ObjectStructure();
o.Attach(new ConcreteElementA());
o.Attach(new ConcreteElementB());
ConcreteVisitor1 v1 = new ConcreteVisitor1();
ConcreteVisitor2 v2 = new ConcreteVisitor2();
o.Accept(v1);
o.Accept(v2);
}
}
public static void main(String[] args) {
ObjectStructure o = new ObjectStructure();
o.Attach(new ConcreteElementA());
o.Attach(new ConcreteElementB());
ConcreteVisitor1 v1 = new ConcreteVisitor1();
ConcreteVisitor2 v2 = new ConcreteVisitor2();
o.Accept(v1);
o.Accept(v2);
}
}
运行结果
ConcreteVisitor1 访问 ConcreteElementA
ConcreteVisitor1 访问 ConcreteElementB
ConcreteVisitor2 访问 ConcreteElementA
ConcreteVisitor2 访问 ConcreteElementB
ConcreteVisitor1 访问 ConcreteElementB
ConcreteVisitor2 访问 ConcreteElementA
ConcreteVisitor2 访问 ConcreteElementB
