set_lag()

void MayaFlux::Buffers::FeedbackProcessor::set_lag	(	size_t	tap,
		Kinesis::TimeMap	seconds,
		double	max_seconds
	)

Drive one tap's lag from a TimeMap.

Parameters

tap	Tap index
seconds	Lag in seconds as a function of seconds processed so far
max_seconds	Largest lag the map may return, sizes the ring

Evaluated once per block and ramped per sample across the block.

Exceptions

std::out_of_range

if tap is not an existing tap
