I am a jackeroo on design. I don't know which pattern I can use with my application.Here is the details:
There are two class(Table,Column) in my application(just describe the database).

I have to get the column value by different manner according to the type of column(for example: the pk column, the column get from the jsp page,the number column and so on).
So I defined an abstract class with the method: Object getValue(). But the parameter maybe different with different column, which pattern can I use? How to do with this ?

Is there any example match this?
Please help!
Thanks!
