新人补钙系列教程之：模拟java多线程Thread类

参照Java的Thread类，写一个Flash的Thread类，这个类调用起来多了一两行代码，但是比较好控制和管理。和Java中Thread类非常相似。

1.  
2. class com.klstudio.util.Thread extends Object{ 
3. private var __mar:Number; 
4. private var __sleep_time:Number; 
5. function Thread(sleepTime:Number){ 
6.   if(sleepTime == undefined){ 
7.    this.__sleep_time = 50; 
8.   }else{ 
9.    this.__sleep_time = sleepTime; 
10.   } 
11. } 
12. private function doRun():Void{ 
13.   this.run(); 
14. } 
15. public function run():Void{   
16. } 
17. public function start():Void{ 
18.   this.__mar = setInterval(this,"doRun",this.__sleep_time); 
19. } 
20. public function stop():Void{ 
21.   clearInterval(this.__mar); 
22. } 
23. public function setSleepTime(sleepTime:Number):Void{ 
24.   this.__sleep_time = sleepTime; 
25. } 
26. public function getSleepTime():Number{ 
27.   return this.__sleep_time; 
28. } 
29. }

testThread.as代码

1. import com.util.Thread; 
2. class testThread extends Thread{ 
3. private var __label_txt:TextField; 
4. function testThread(){ 
5.   super(1000); 
6.   this.init(); 
7. } 
8. private function init():Void{ 
9.   _root.createTextField("label_txt", 4, 0, 0, 100, 20);   
10.   this.__label_txt = _root["label_txt"]; 
11.   this.initLabel(); 
12.   this.start(); 
13. } 
14. private function initLabel():Void{ 
15.   this.__label_txt.autoSize = "left"; 
16.   this.__label_txt.html = false; 
17.   this.__label_txt.textColor = 0x000000; 
18.   this.__label_txt.wordWrap = false; 
19.   this.__label_txt.type = "dynamic"; 
20.   this.__label_txt.selectable = false; 
21. } 
22. private function run():Void{ 
23.   var today:Date = new Date(); 
24.   var lbl:String = (today.getHours() < 10 ? "0" + today.getHours() : today.getHours()) + ":" + (today.getMinutes() < 10 ? "0" + today.getMinutes() : today.getMinutes()) + ":" + (today.getSeconds() < 10 ? "0" + today.getSeconds() : today.getSeconds()); 
25.   this.__label_txt.text = lbl; 
26. } 
27. }

Flash调用代码片段：

1. stop(); 
2. var tt:testThread = new testThread();
