[rules-users] -Uploading modified output file

Hi, I have data from a text file (consists of 2 columns : A and B with data respectively)which is read and stored into a Vector <Objects>. I have multiple input files with 2 columns of data so used Vector<Objects>. This collection of data is loaded to my rule runner which loads data in the rulebase and fires rules on that data. 1. how do I upload the modified data output into another text file? Should I reload it in a vector? But whenever rule is fired and data is modified how can I store the modified data in another file? Because my input and output has different columns. 1. is using a vector a bad way?? Could I do it in any other better way? 2. how can I identify what my A and B columns are- to load the specific rule only?? As of now I am just reading its name and storing it. Could I do it in a better way??? Please help!! Thankyou.
