Assume you have a column family named "testCF" with comparator *
CompositeType*(AsciiType, IntegerType(reversed=true), IntegerType); and a
few columns have been inserted into record key "a".
____________________________________
Composite start = new Composite() ;
Composite end = new Composite() ;
start.addComponent("abc", StringSerializer.get()) ;
end.addComponent("abc", StringSerializer.get(), "UTF8Type",
AbstractComposite.ComponentEquality.GREATER_THAN_EQUAL) ;
SliceQuery<String, ByteBuffer, ByteBuffer> query =
HFactory.createSliceQuery(keyspace, StringSerializer.get(),
ByteBufferSerializer.get(), ByteBufferSerializer.get());
query.setKey("a");
query.setColumnFamily("testCF");
query.setRange(start.serialize(), end.serialize(), false, 100);
List<HColumn<ByteBuffer, ByteBuffer>> columns =
query.execute().get().getColumns();
