Examples of org.apache.cassandra.io.util.DataOutputBuffer

org.apache.cassandra.io.util.DataOutputBuffer
An implementation of the DataOutputStream interface. This class is completely thread unsafe.

        ByteBuffer key = ByteBuffer.wrap("k".getBytes());
        RowMutation rm = new RowMutation("Keyspace1", key);
        for (int i = 0; i < 1000; i++)
            rm.add(new QueryPath("Standard1", null, ByteBufferUtil.bytes(i)), ByteBufferUtil.EMPTY_BYTE_BUFFER, 0);
        rm.apply();
        DataOutputBuffer out = new DataOutputBuffer();
        RowMutation.serializer.serialize(rm, out, MessagingService.current_version);
        assert out.getLength() > DatabaseDescriptor.getColumnIndexSize();
        cfs.forceBlockingFlush();


        assertBytes(cfs, Integer.MAX_VALUE);
        assertDigest(cfs, Integer.MAX_VALUE);
