Examples of org.apache.cassandra.thrift.ColumnOrSuperColumn$ColumnOrSuperColumnTupleSchemeFactory

org.apache.cassandra.thrift.ColumnOrSuperColumn
Methods for fetching rows/records from Cassandra will return either a single instance of ColumnOrSuperColumn or a list of ColumnOrSuperColumns (get_slice()). If you're looking up a SuperColumn (or list of SuperColumns) then the resulting instances of ColumnOrSuperColumn will have the requested SuperColumn in the attribute super_column. For queries resulting in Columns, those values will be in the attribute column. This change was made between 0.3 and 0.4 to standardize on single query methods that may return either a SuperColumn or Column. If the query was on a counter column family, you will either get a counter_column (instead of a column) or a counter_super_column (instead of a super_column) @param column. The Column returned by get() or get_slice(). @param super_column. The SuperColumn returned by get() or get_slice(). @param counter_column. The Counterolumn returned by get() or get_slice(). @param counter_super_column. The CounterSuperColumn returned by get() or get_slice().
