How to import large TTL file into named graph into TDB?

[Wang Dongsheng]

HI,
  It's good to use
TDBLoader.load(TDBInternal.getBaseDatasetGraphTDB(datasetGraph),file,
false); to load large TTL files into TDB.
   But, I want to name the graph, maybe something liked
"dataset.addNamedModel(graphName, Model)"  As we know, this method is
slow and limited to fast and large file importing.
   Is there any similar function for the TDBLoader cass that I can
name a graphName?

Thanks in advance~!
