What is Object Oriented Scanner (Lexical Analysis)?

R开发者_如何转开发ecently I came across the concept of Lexical Analysis called "Object Oriented Scanner", but I wasn't able to distinguish it from the normal scanning technique. What can be the extra things in object oriented scanner, please help me understanding this concept... what can be object orientation in terms of Lexical analysis?

This should interest you, it is the theory behind oolex.

You should also look into the theory behind object oriented scanners, as in the proceedings of CompSysTech 2000: CompSysTech '00 Proceedings of the conference on Computer systems and technologies, where "From structure oriented to object oriented scanner design" was published. You will need a membership from the ACM if you can't find it in your university's library, but you can check this and this in the meantime. The last link is some Java with appropriate explanations.
