libtcspc.SinkEvents¶

final class libtcspc.SinkEvents(*event_types)[source]¶

Bases: Node

Sink that accepts and discards a fixed set of event types.

Most useful for testing, or for asserting at graph-build time that an upstream subgraph only produces a known set of event types — any other event type connected to this sink is rejected at graph build time.

Parameters:: *event_types (EventType) – The only event types the sink will accept.

Notes

Events handled:

Events matching one of event_types: ignored.
Events not in event_types: rejected at graph build time.
End of input: ignored.
