org.apache.cassandra.db.composites.Composite
A composite value. This can be though as a list of ByteBuffer, except that this also include an 'end-of-component' flag, that allow precise selection of composite ranges. We also make a difference between "true" composites and the "simple" ones. The non-truly composite will have a size() == 1 but differs from true composites with size() == 1 in the way they are stored. Most code shouldn't have to care about the difference.

            return true;


        if (start().isEmpty() || finish().isEmpty() || !cf.hasColumns())
            return false;


        Composite low = isReversed() ? finish() : start();
        Composite high = isReversed() ? start() : finish();


        CellName first = cf.iterator(ColumnSlice.ALL_COLUMNS_ARRAY).next().name();
        CellName last = cf.reverseIterator(ColumnSlice.ALL_COLUMNS_ARRAY).next().name();


        return cf.getComparator().compare(first, low) <= 0
