模式
代理模式支持将某些操作从实际的对象中分离出来，通过它的代理类提供处理。这样便于修改和管理这些特定的操作。
下面示例一个代理模式的实现。
<<interface>>Subject.java
package
com.zj.proxy;
public
interface
Subject {
void
operation1();
void
operation2(String arg);
}
现实类
RealSubject.java
package
com.zj.proxy;
public
class
RealSubject
implements
Subject {
public
void
operation1() {
System.
out
.println(
"Realer do operation1"
);
}
public
void
operation2(String arg) {
System.
out
.println(
"Realer do operation2 with "
+ arg);
}
}
代理类
ProxySubject.java
package
com.zj.proxy;
public
class
ProxySubject
implements
Subject {
private
Subject
proxied
;
//
被代理对象
public
ProxySubject(Subject
proxied) {
this
.
proxied
= proxied;
}
public
void
operation1() {
System.
out
.println(
"Proxyer do operation1"
);
proxied
.operation1();
}
public
void
operation2(String arg) {
System.
out
.println(
"Proxyer do operation2 with "
+ arg);
proxied
.operation2(arg);
}
}
