stepKey constant

Symbol const stepKey

The zone key a device's step travels under — the tap, by a person or an agent, that caused the request. The adapter reads it from the request's x-fw-step header and puts it in the zone beside requestIdKey; every event emitted below it then carries it as step, so one tap's consequences — queries, messages, broadcasts — gather as one trace.

Implementation

static const Symbol stepKey = #fwStep;
