Examples of IDiskAtomFilter

org.apache.cassandra.db.filter.IDiskAtomFilter
Given an implementation-specific description of what columns to look for, provides methods to extract the desired columns from a Memtable, SSTable, or SuperColumn. Either the get*ColumnIterator methods will be called, or filterSuperColumn, but not both on the same object. QueryFilter takes care of putting the two together if subcolumn filtering needs to be done, based on the querypath that it knows (but that IFilter implementations are oblivious to).

            IPartitioner p = StorageService.getPartitioner();
            IndexExpression expr = new IndexExpression(ByteBufferUtil.bytes("birthdate"),

            List<IndexExpression> clause = Arrays.asList(expr);
            IDiskAtomFilter filter = new IdentityQueryFilter();
            Range<RowPosition> range = Util.range("", "");
            List<Row> rows = cfs.search(clause, range, 100, filter);
