Examples of nexj.core.meta.persistence.file.FileDataSourceFragment

nexj.core.meta.persistence.file.FileDataSourceFragment
The metadata object representing a file data source fragment. Each fragment contains all of the configuration parameters necessary to establish a "connection" to a different data directory.

         //Interpret badly-formatted OID as "not found"
         return new InstanceArrayList(0);
      }


      //Open file directly
      FileDataSourceFragment fragment = (FileDataSourceFragment)query.getFragment();
      File dataFile = nexj.core.rpc.file.ra.FileManagedConnection.splitNameToSubdirs(
         new File(fragment.getDataDirectory()), sDataFileName,
            fragment.getMaxNameSplits(), fragment.getNameSplitSize(), false);


      if (!dataFile.exists())
      {
         //Not found
         return new InstanceArrayList(0);
