MacroCommand
public class MacroCommand implements Command {
Command[] commands;
public MacroCommand(Command[] commands) {
this.commands = commands;
}
public void execute() {
for (int i = 0; i < commands.length; i++) {
commands[i].execute();
}
}
public void undo() {
for (int i = 0; i < commands.length; i++) {
commands[i].undo();
}
}
}
MacroCommand最主要的就是这个宏命令，是命令的集合 test
/**
*
*/
public class Test {
public static void main(String[] args) {
RemoteControl remoteControl = new RemoteControl();
Light light = new Light("Living Room");
TV tv = new TV("Living Room");
|
| Stereo stereo = new Stereo("Living Room"); Hottub hottub = new Hottub(); LightOnCommand lightOn = new LightOnCommand(light); StereoOnCommand stereoOn = new StereoOnCommand(stereo); TVOnCommand tvOn = new TVOnCommand(tv); HottubOnCommand hottubOn = new HottubOnCommand(hottub); LightOffCommand lightOff = new LightOffCommand(light); StereoOffCommand stereoOff = new StereoOffCommand(stereo); TVOffCommand tvOff = new TVOffCommand(tv); HottubOffCommand hottubOff = new HottubOffCommand(hottub); Command[] partyOn = { lightOn, stereoOn, tvOn, hottubOn }; Command[] partyOff = { lightOff, stereoOff, tvOff, hottubOff }; MacroCommand partyOnMacro = new MacroCommand(partyOn); MacroCommand partyOffMacro = new MacroCommand(partyOff); remoteControl.setCommand(0, partyOnMacro, partyOffMacro); System.out.println(remoteControl); System.out.println("--- Pushing Macro On---"); remoteControl.onButtonWasPushed(0); System.out.println("--- Pushing Macro Off---"); remoteControl.offButtonWasPushed(0); |
} | } |
Command[] partyOn = { lightOn, stereoOn, tvOn, hottubOn };
Command[] partyOff = { lightOff, stereoOff, tvOff, hottubOff };
MacroCommand partyOnMacro = new MacroCommand(partyOn); MacroCommand partyOffMacro = new MacroCommand(partyOff);
关键就是这几个命令
kk
设计模式(14)----- 命令设计模式（升级----一个命令对象执行多条命令）
