Method●Since v1.3

push

Copy
push(ns: Namespace, event: ProtocolEvent)
View source on GitHub

Parameters

NameTypeDescription
ns*Namespace

Target namespace for the synthetic event.

event*ProtocolEvent

The event envelope to inject. event.seq is overwritten by the mux; callers can pass any placeholder.

Injects a new ProtocolEvent into the mux pipeline. The event is routed through every registered transformer (including the emitting transformer — implementers must guard against re-entrant self-processing) and, if not suppressed, appended to the main event log.
