* \brief All-to-all stream annotator testing block. FOR TESTING PURPOSES ONLY.
38
*
39
* This block creates tags to be sent downstream every 10,000 items it sees. The
40
* tags contain the name and ID of the instantiated block, use "seq" as a key,
41
* and have a counter that increments by 1 for every tag produced that is used
42
* as the tag's value. The tags are propagated using the all-to-all policy.
43
*
44
* It also stores a copy of all tags it sees flow past it. These tags can be
45
* recalled externally with the data() member.
46
*
47
* This block is only meant for testing and showing how to use the tags.
