Yes. You can use result.rawCells() to get the array of Cell instances backing your query, if you need to retrieve all columns in your row at once. You can then retrieve column values in the same way as above from each Cell instance.
Alternatively, if your requirement is to process each column one by one, you can use result.cellScanner() to get a CellScanner instance (say "cellScanner"), and then iterate over each cell through cellScanner.current(). Please see [1] for all operations supported by org.apache.hadoop.hbase.client.Result.
