  • To get the number of rows in an IMDC, use the numRows() method:
    {
      InMemoryDataCollection IMDC_name =
        InMemoryDataCollectionRepository.getInMemoryDataCollection(imdcName_);
    
      if (IMDC_name != null)
      {
        for (InMemoryDataCollectionColumnInfo colInfo : imdcColInfoList) {
          outputEmitter.addLong(IMDC_name.numRows());
      
        outputEmitter.emitRow();
      }
    }
