Classes
struct	pulp::dataplane::detail::PublishedValue< T >
struct	pulp::dataplane::MeterFrame
	A single multi-channel meter reading. More...
class	pulp::dataplane::PublishCounter
	Monotonic publish counter, shared by every value source. More...
class	pulp::dataplane::MeterSource
	Lock-free meter channel: the host publishes a MeterFrame from the audio/host thread; the view reads the latest frame paint-safe. More...
struct	pulp::dataplane::VectorFrame
	A block of samples for a scope-style display — an envelope curve, a detector's output, a window of the signal a processor is actually working on. More...
struct	pulp::dataplane::ValueEvent
	One occurrence inside an audio block. More...
struct	pulp::dataplane::EventFrame
	A bounded list of occurrences from one audio block. More...
class	pulp::dataplane::VectorSource
	Lock-free vector channel: the writer publishes a block of samples, the view reads the latest block paint-safe. More...
class	pulp::dataplane::EventSource
	Lock-free event channel: the writer publishes the occurrences from one audio block and the view reads the latest completed block. More...
class	pulp::dataplane::ScalarSource
	Lock-free scalar channel: a single paint-safe cached number (a readout value, a modulation ring's base→modulated position). More...

Detailed Description

Paint-safe host→view value channels.

A plugin's audio/host thread publishes meter levels, a scalar readout, or bounded occurrences; a view reads the latest value paint-safe on the FrameClock — no lock, no allocation on either side. This is the SDK default for the pattern every native-import host otherwise hand-rolls (a reader polled on the frame clock), and the subscription that lets a live meter keep an editor's frames alive (see needs_continuous_frames).
