Examples of org.apache.cassandra.db.filter.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).

        // verify we get it back w/ index query too
        IndexExpression expr = new IndexExpression(COLUMN, IndexExpression.Operator.EQ, VALUE);
        List<IndexExpression> clause = Arrays.asList(expr);
        IDiskAtomFilter filter = new IdentityQueryFilter();
        Range<RowPosition> range = Util.range("", "");
        rows = keyspace.getColumnFamilyStore(CF1).search(range, clause, filter, Integer.MAX_VALUE);
        assertEquals(LOOPS, rows.size());


        // we don't allow cleanup when the local host has no range to avoid wipping up all data when a node has not join the ring.
