Examples of org.apache.thrift.TSerializer

org.apache.thrift.TSerializer
Generic utility for easily serializing objects into a byte array or Java String.

        ByteBuffer sc = sliceCommand.super_column;
        dos.writeInt(sc == null ? 0 : sc.remaining());
        if (sc != null)
            ByteBufferUtil.write(sc, dos);


        TSerializer ser = new TSerializer(new TBinaryProtocol.Factory());
        FBUtilities.serialize(ser, sliceCommand.predicate, dos);
        AbstractBounds.serializer().serialize(sliceCommand.range, dos);
        dos.writeInt(sliceCommand.max_keys);
    }

      System.out.println("Avg time: " + timeAvg/1000 + "us");
