flex 多态例子

1：写个接口
package com.interfacePoly
{
public interface MyInterface
{
function interfaceOne():void;
function interfaceTwo():void;
function interfaceThree():void;

}
}

2：写2个实现接口的类
a,
package com.interfacePoly
{
import mx.controls.Alert;
public class ImpInterfaceOne implements MyInterface
{
public function ImpInterfaceOne()
{
}

public function interfaceOne():void
{
Alert.show("one.......1");
}

public function interfaceTwo():void
{
Alert.show("one......2");
}

public function interfaceThree():void
{
Alert.show("one......3");
}

}
}

b,
package com.interfacePoly
{
import mx.controls.Alert;
public class ImpInterfaceTwo implements MyInterface
{
public function ImpInterfaceTwo()
{
}

public function interfaceOne():void
{
Alert.show("Two......1");
}

public function interfaceTwo():void
{
Alert.show("Two......2");
}

public function interfaceThree():void
{
Alert.show("Two.....3");
}

}
}

3:实现多态的类
package com.interfacePoly
{
public class Imp
{
public function Imp()
{
}
public function interfaceOne(interface1:MyInterface):void
{
interface1.interfaceOne();
}
public function interfaceTwo(interface2:MyInterface):void
{
interface2.interfaceTwo();
}

}
}
4：调用
