    - #### cas

          CASResult cas(java.nio.ByteBuffer key,
                        java.lang.String column_family,
                        java.util.List<Column> expected,
                        java.util.List<Column> updates,
                        ConsistencyLevel serial_consistency_level,
                        ConsistencyLevel commit_consistency_level)

                        UnavailableException,
                        TimedOutException,
                        org.apache.thrift.TException

      Atomic compare and set. If the cas is successfull, the success boolean in CASResult will be true and there will be no current_values. Otherwise, success will be false and current_values will contain the current values for the columns in expected (that, by definition of compare-and-set, will differ from the values in expected). A cas operation takes 2 consistency level. The first one, serial_consistency_level, simply indicates the level of serialization required. This can be either ConsistencyLevel.SERIAL or ConsistencyLevel.LOCAL_SERIAL. The second one, commit_consistency_level, defines the consistency level for the commit phase of the cas. This is a more traditional consistency level (the same CL than for traditional writes are accepted) that impact the visibility for reads of the operation. For instance, if commit_consistency_level is QUORUM, then it is guaranteed that a followup QUORUM read will see the cas write (if that one was successful obviously). If commit_consistency_level is ANY, you will need to use a SERIAL/LOCAL_SERIAL read to be guaranteed to see the write.
      Parameters:
        `key` -
        `column_family` -
        `expected` -

        `column_path` -
        `timestamp` -

                              org.apache.thrift.TException
