处理TC的Command问题

需求：因为TC的Command执行操作是，是另起一个线程，那么该怎么知道它是否结束该线程了？

解决方法，给Command添加一个监听事件

isCommandFinish = true;
if(deleteTcContextList.size()> 0){
　　isCommandFinish = false;
　　AIFComponentContext[] tcContexts = new AIFComponentContext[deleteTcContextList.size()];
　　tcContexts = deleteTcContextList.toArray(tcContexts);
　　DeleteCommand deleteCommand = new DeleteCommand(tcContexts,app.getDesktop());
　　deleteCommand.addCommandListener(new ICommandListener() {
							
　　@Override
　　public void commandStarting(ICommandListenerEvent paramICommandListenerEvent) {
　　　　// TODO Auto-generated method stub
	System.out.println("command开始！！");
　　}
    @Override
　　 public void commandDone(ICommandListenerEvent paramICommandListenerEvent) {
	// TODO Auto-generated method stub
	isCommandFinish = true;
　　}
});
deleteCommand.executeModeless();
}
