Hi,
hmm, I tried the following but it does not seem to work (dataset is never
found).
String directory = DBpath.concat("/" + datasetID);
Location loc = Location.mem(directory);
boolean isbacked = loc.exists();
if (isbacked) {
log.debug("=> Found dataset to be deleted.");
} else {
log.debug("=> dataset to be deleted not found.");
}
Maybe it's the way I initialize the Location?
BTW, how does one remove a dataset from a TDB store?
I didn't see a dedicated API call for this.
Cheers,
Hubert
