Examples of org.apache.cassandra.thrift.KeyRange

org.apache.cassandra.thrift.KeyRange
The semantics of start keys and tokens are slightly different. Keys are start-inclusive; tokens are start-exclusive. Token ranges may also wrap -- that is, the end token may be less than the start one. Thus, a range from keyX to keyX is a one-element range, but a range from tokenY to tokenY is the full ring.

         String startKey = "";


         // Get the keys in SLICE_SIZE blocks
         int sliceSize = Math.min(SLICE_SIZE, numEntries);
         for (boolean complete = false; !complete;) {
            KeyRange keyRange = new KeyRange(sliceSize);
            keyRange.setStart_token(startKey);
            keyRange.setEnd_token("");
            List<KeySlice> keySlices = cassandraClient.get_range_slices(entryColumnParent,
                     slicePredicate, keyRange, readConsistencyLevel);


            // Cycle through all the keys
            for (KeySlice keySlice : keySlices) {
