Examples of org.apache.thrift.TDeserializer

org.apache.thrift.TDeserializer
Generic utility for easily deserializing objects from a byte array or Java String.

        int scLength = dis.readInt();
        ByteBuffer super_column = null;
        if (scLength > 0)
            super_column = ByteBuffer.wrap(readBuf(scLength, dis));


        TDeserializer dser = new TDeserializer(new TBinaryProtocol.Factory());
        SlicePredicate pred = new SlicePredicate();
        FBUtilities.deserialize(dser, pred, dis);


        AbstractBounds range = AbstractBounds.serializer().deserialize(dis);
        int max_keys = dis.readInt();
