Interface ICanProvideEventStreamId

Namespace

Cratis.Chronicle.Events

Assembly

Cratis.Chronicle.dll

Defines a reactor that can dynamically provide the EventStreamId to use when appending side-effect events returned from handler methods.

Remarks

Implement this interface on a reactor class to supply a runtime stream ID. For a fixed compile-time value, apply the EventStreamIdAttribute to the reactor type instead. When both this interface and the attribute are present on the same reactor type, the interface takes priority and the attribute value is ignored.

Methods

GetEventStreamId()

Gets the EventStreamId to use when appending side-effect events.

EventStreamId GetEventStreamId()

Returns

EventStreamId

The EventStreamId.
