What is the meaning for this, please let me know:

we never look it up once it has been used the first time

More context please.

I'm sorry, I don't have it right now. I saw it on one Java forum while learning something.
I will post it later, and thanks Dozy !

I just found it, I think, at http://code.google.com/p/selenium/wiki/PageFactory , if that's the same thing.

I think it just means that the "look up" procedure (i.e. the process of trying to find the thing, whatever it is) is only invoked once, when the item is first used/requested. Once that has been done once, there is no need to keep repeating the procedure .
