Batcher Protocol SplitterV2

SplitterV2 accepts one Batcher v2 super-frame and emits one Rogue stream frame per contained record.

Protocol reference: https://confluence.slac.stanford.edu/x/L2VlK

Behavior summary

• Input is parsed with CoreV2.

• Each parsed Data record becomes one output frame.

• Output frame metadata is mapped as: channel <- destination, firstUser <- first-user, lastUser <- last-user.

Python example

import rogue.protocols.batcher
import rogue.interfaces.stream

src = MyBatcherV2Source()
split = rogue.protocols.batcher.SplitterV2()
filt = rogue.interfaces.stream.Filter(True, 3)  # Keep destination/channel 3
dst = MyRecordSink()

src >> split >> filt >> dst
