I am currently using a method I made which just uses Apache FileUtils to
delete the folder containing my TDB, but if I add named models to the
Dataset, the models will still be accessible in memory even after the
physical models are gone. If I called addNamedModel it will tell me the
model already exists when I delete the TDB folder and re-create it. How can
I fix this?
Why do you want to delete the folder?
What exactly is the dataset you are using?
Deleting files behind TDB's back can only be done with great care. You
must use StoredConnection.release() to expel it from the in-JVM cache.
Then delete the files, then reopen it the database.
Otherwise, the caches are still there and some of your data is still
around. Eventually something will go wrong. Such data is not persistent.
This does not work on Windows/64bit. This is a well-documented issue on
MS Windows with memory mapped files.
