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);
}
}
运行结果
ConcreteVisitor1 访问 ConcreteElementA
ConcreteVisitor1 访问 ConcreteElementB
ConcreteVisitor2 访问 ConcreteElementA
ConcreteVisitor2 访问 ConcreteElementB
