Fetching columns for a row preserving data types.

[Vamshi]

Hi,

 When I fetch columns using SliceQuery, it returns me all the columns with the same datatype. Is there any way that QueryResult have object as the datatype of column values.
I can use instance of operator and then typecast it to any datatype.

Code snippet:

        SliceQuery<String,String,ByteBuffer> query = HFactory.createSliceQuery(getConnection().getKeyspace(),StringSerializer.get(),StringSerializer.get(),ByteBufferSerializer.get());
        query.setColumnFamily(columnFamily).setKey(key).setRange("","",false,100);
        QueryResult<ColumnSlice<String, ByteBuffer>> colResult = query.execute();

In the above code snippet, I am getting ByteBuffer of all the values. Can I get Object in place of it?

Regards,
Vamshi

Convert the ByteBuffer using the appropriate serializer. For example,
to convert the ByteBuffer to a String use:

ByteBuffer buffer = column.getValue();
String value = StringSerializer.get().fromByteBuffer(buffer);

Hi Vamshi

Can you paste your final code here? Actually I am facing same problem and the
thing is I dont know the data type of column values in advance. So we have to
dynamically find that out and then use frombytebuffer accordingle. Can you
provide some help?
