工具类：延迟执行队列

代码：

package Common.Utils
{
    public class DelayRefreshQueue
    {
        private static var _queue:Object=new Object();//"uiclassname" : [{"caller":*,"method":funciton,"args"=[a,b...]},...]
        
        public function DelayRefreshQueue()
        {
        }
        
        public static function addRefreshTask(uiname:String,caller:*,method:Function,args:Array):void
        {
            if(_queue[uiname])
            {
                if(!checkLastRefreshIsSame(uiname,caller,method,args))
                    _queue[uiname].push({caller:caller,method:method,args:args});
            }else
            {
                _queue[uiname] = new Array();
                _queue[uiname].push({caller:caller,method:method,args:args});
            }
        }
        
        public static function doRefreshTask(uiname:String,caller:*):void
        {
            if(_queue[uiname])
            {
                for(var i:int=0;i<_queue[uiname].length;i++)
                {
                    if(_queue[uiname][i].caller == caller)
                    {
                        _queue[uiname][i].method.apply(_queue[uiname][i].caller,_queue[uiname][i].args);
                        (_queue[uiname] as Array).splice(i,1);
                        i--;
                    }
                }
                if((_queue[uiname] as Array).length==0)
                {
                    //删除
                    _queue[uiname] = null;
                    delete _queue[uiname];          
                }
            }
        }
        
        //检测上一次是否跟这次一样 
        private static function checkLastRefreshIsSame(uiname:String,caller:*,method:Function,args:Array):Boolean
        {
            if( _queue[uiname])
            {
                var last:Array = _queue[uiname] as Array;
                var obj:Object = last[last.length-1];
                if(obj)
                {
                    if(obj.caller == caller && obj.method == method)
                    {
                        if(args==null&&obj.args==null)
                        {
                            return true;
                        }else
                        {
                            for(var i:int=0;i

使用示例

//构造函数中定义：
DelayRefreshQueue.doRefreshTask("TacticalDlg",this);
//延迟某个方法到队列中
DelayRefreshQueue.addRefreshTask("TacticalDlg",this,refreshUI,null);

使用拓展

1、设置一个资源加载/创建是否完成的变量
2、如果资源加载/创建未完成，就使用addRefreshTask将某个方法/函数延迟到队列中
