com.netflix.astyanax.serializers.ByteBufferOutputStream
Utility to collect data written to an {@link OutputStream} in{@link ByteBuffer}s. Originally from org.apache.avro.util.ByteBufferOutputStream, moved into Hector and added getByteBuffer to return single ByteBuffer from contents.

    public ByteBuffer serialize() {
        if (serialized != null) {
            return serialized.duplicate();
        }


        ByteBufferOutputStream out = new ByteBufferOutputStream();


        int i = 0;
        for (Component c : components) {
            Serializer<?> s = serializerForPosition(i);
            ByteBuffer cb = c.getBytes(s);
            if (cb == null) {
                cb = ByteBuffer.allocate(0);
            }


            if (dynamic) {
                String comparator = comparatorForPosition(i);
                if (comparator == null) {
                    comparator = c.getComparator();
                }
                if (comparator == null) {
                    comparator = ComparatorType.BYTESTYPE.getTypeName();
                }
                int p = comparator.indexOf("(reversed=true)");
                boolean desc = false;
                if (p >= 0) {
                    comparator = comparator.substring(0, p);
                    desc = true;
                }
                if (aliasToComparatorMapping.inverse().containsKey(comparator)) {
                    byte a = aliasToComparatorMapping.inverse().get(comparator);
                    if (desc) {
                        a = (byte) Character.toUpperCase((char) a);
                    }
                    out.writeShort((short) (0x8000 | a));
                }
                else {
                    out.writeShort((short) comparator.length());
                    out.write(ByteBufferUtil.bytes(comparator));
                }
            }
            out.writeShort((short) cb.remaining());
            out.write(cb.slice());
            out.write(c.getEquality().toByte());
            i++;
        }


        serialized = out.getByteBuffer();
        return serialized.duplicate();
    }
