You can use dir.listFiles() and it will return list of files in that dir.
You can iterate over the list to check for any TDB file present and then
load Dataset from it.

There will be (next release) "TDBFactory.inUseLocation" which has some 
checks, the main one being for the file "tdb.cfg".


(Older versions of TDB may not have created this file.)

Hello,

I want to load a Dataset from a directory but not to create a new one if
there is no TDB files in this directory. Is there a way to check that TDB
files effectively exist in a directory or to load a Dataset while
preventing to create files on disk if they don't exist ?

Thank you.

Hi Laurent

You can use dir.listFiles() and it will return list of files in that dir.
You can iterate over the list to check for any TDB file present and then
load Dataset from it.

Check the Jena TDB files exist in a directory

[Laurent Rucquoy]

Hello,

I want to load a Dataset from a directory but not to create a new one if
there is no TDB files in this directory. Is there a way to check that TDB
files effectively exist in a directory or to load a Dataset while
preventing to create files on disk if they don't exist ?

Thank you.

Sincerely,
Laurent
