That's what i was thinking about.
I Have a file in the filesystem that i am reading and I would like to
record the position I stop reading before I record the object that reads
the file, so when I de-serialize that object I could use it and continue
reading the same file in the recorded position.
How Do you think i can deal with this situation ?
Thank you
