libtcspc.ConvertSequencesToStartStop¶

final class libtcspc.ConvertSequencesToStartStop(tick_event_type, start_event_type, stop_event_type, count)[source]¶

Bases: Node

Processor that converts tick sequences to gapless start-stop event pairs.

Every count + 1 tick_event_type events are replaced by a series of start_event_type and stop_event_type events bracketing each tick interval. Other events pass through.

Parameters:

tick_event_type (EventType) – The tick event type (consumed). Must have an abstime field.
start_event_type (EventType) – The emitted start event type. Must be brace-initializable and have an abstime field.
stop_event_type (EventType) – The emitted stop event type. Must be brace-initializable and have an abstime field.
count (int or Param[int]) – Number of intervals per sequence.

Notes

Events handled:

tick_event_type: every count + 1 ticks are replaced by a series of start_event_type and stop_event_type events bracketing each tick interval.
All other event types: pass through unchanged.
End of input: pass through; an incomplete (partial) sequence is discarded.
