Examples of org.apache.cassandra.thrift.SuperColumn$SuperColumnTupleScheme

org.apache.cassandra.thrift.SuperColumn
A named list of columns. @param name. see Column.name. @param columns. A collection of standard Columns. The columns within a super column are defined in an adhoc manner.Columns within a super column do not have to have matching structures (similarly named child columns).

            List<Column> columns = new ArrayList<Column>(1);
            Column col = new Column(columnName);
            col.setValue(value);
            col.setTimestamp(microTimestamp());
            columns.add(col);
            cosc.setSuper_column(new SuperColumn(superColumn, columns));
         } else {
            Column col = new Column(columnName);
            col.setValue(value);
            col.setTimestamp(microTimestamp());
            cosc.setColumn(col);
