44  * @brief Templated interface class to index packet types.
45  *
46  * @ingroup ocsd_interfaces
47  *
48  * Each protocol version will have an associated indexer that will index significant
49  * packets such as synchronisation points, timestamps, trigger events.
50  *
51  * Creating an index is optional at runtime, but will allow any analysis program to synchronise the
52  * different trace streams.
53  *
54  * Indexes need to be created only once and can be saved for re-use.
55  *
56  * Packet processors should be created to support the attachment of an indexer.
