请你不要介意我用很烂的英语来表达,当作写英语报告练习.
When it comes to use 'wait'method ,I find that inapplicable.
That's not the way I see fit.
We must wait until the object turn up.if passed 5 seconds,we still waiting for the object ?
so we can make a judgement and defines a set of object to your ObjectRepository ,for example:
if object.exist then
......
else
......
end if
