Event¶

Bases: MutableMapping[QualifiedName | str, Any]

Reusable server-side event draft.

Construct with o6.Event(server, ...) and trigger as often as needed. Construction does not access the address space or emit an event. As a mutable mapping of event fields, it supports dict(event), len(event), del event[key], and iteration. The attributes below can be reassigned between triggers.

Field keys are event-filter path strings such as "/BatchId", or QualifiedName values when a namespace matters.

When eventType is None, each trigger() resolves it from eventInstance's type if supplied, otherwise from source's declared GeneratesEvent target. The draft itself keeps eventType=None.

See Events.
