pattern() [3/4]

template<std::incrementable Index = uint64_t, typename Generator , typename Callback >
requires PatternGenerator<Generator, Index> && PatternCallback<Callback, typename PatternTraits<Generator, Index>::value_type>

std::shared_ptr< Vruta::Routine > MayaFlux::Kriya::pattern	(	Generator	generator,
		Callback	callback,
		std::vector< double >	durations,
		Vruta::ProcessingToken	token = Vruta::ProcessingToken::SAMPLE_ACCURATE
	)

Creates a pattern whose steps are spaced by a list of durations.

Template Parameters

Index

Step index type, default uint64_t

Parameters

generator	Callable from the step index to any value
callback	Callable that takes the generated value
durations	Seconds to wait after each step, stepped through in order and repeated
token	Selects the routine type that runs the pattern

Returns

The routine, or nullptr for an empty function, an empty list or an unsupported token

The first step runs at once. After step i the routine waits durations[i % size], rounded to the routine's own units and never less than one unit. A single interval is a list of one: pattern(gen, cb, { 0.125 }). A throw from the generator or callback is logged and ends the pattern.

auto routine = Kriya::pattern(generate, apply, { 0.25, 0.25, 0.5 });
scheduler->add_task(routine);
