Difference between two locations

[chetna chaudhari]

Hi ,
     I am new to journal.io.api and facing some issues, can someone help me out please .

1) Do we have any way to access the last know location of journal. One way here is that maintaining the return value of journal.write function. But facing issue, how to fetch it on the start of application.

2) Is there any way to get exact difference between two Locations? I can see the Location.compareTo(Location) function, but it either returns difference between file Id's or if file Id's are same then difference between file pointers.

Thanks.
