Sebastian Schelter commented on MAHOUT-441:
-------------------------------------------
Sorry I did a lot of file renaming when creating the first patch, must have
messed things up. I added a fresh and hopefully clean version.
> File-backed IDMigrator

> To complete taste's suite of file-related implementations (currently
> FileDataModel and FileItemSimilarity) I created an IDMigrator backed by a
> file. It can be refreshed and will reload it's data into memory in the same
> way FileDataModel and FileItemSimilarity are already doing this.
> I couldn't prevent having to split up the IDMigrator interface into 2
> separate interfaces because the update methods (like storeMapping(...) and
> initialize(...)) did not fit in the concept of reloading data from an
> external source, hope that's ok.
