Detailed Description

A bounded list of occurrences from one audio block.

Fixed capacity keeps the payload trivially copyable for TripleBuffer. Publishers call publish() only for blocks they want the UI to observe; an empty frame is valid but carries no occurrence to dispatch.

count

int pulp::dataplane::EventFrame::count = 0

events

std::array<ValueEvent, kMaxEvents> pulp::dataplane::EventFrame::events {}

kMaxEvents

int pulp::dataplane::EventFrame::kMaxEvents = 1024

publication

std::uint32_t pulp::dataplane::EventFrame::publication = 0

Source-owned generation used by a reader to identify this exact block.

Unlike PublishCounter, this travels atomically with the payload, so a publish racing the UI snapshot cannot duplicate the newest block.
