Interface IEventUpcasterPipeline

Namespace: Stratara.Abstractions.EventSourcing

Assembly: Stratara.Abstractions.dll

Applies the registered IEventUpcaster chain to a persisted event payload on read, before the payload is resolved to a runtime type and deserialized. Consumed by the event-mapping layer; a host with no upcasters registered gets a transparent pass-through.

public interface IEventUpcasterPipeline

Extension Methods: FieldChangedEventExtensions.ApplyPropertyChanged<TAggregate>(TAggregate, FieldChangedEvent<TAggregate>)

EventStream.ApplyEvents(object, IReadOnlyList<IEvent>)

Remarks

Implementations resolve upcasters by SourceEventTypeName (version- independent match) and apply them in sequence — the target of one hop becomes the source lookup for the next — until no upcaster matches the current type name.

Methods

Upcast(string, string)

Runs the upcaster chain for a single persisted event.

UpcastedEvent Upcast(string eventTypeName, string dataJson)

Parameters

eventTypeName string: The event type name as persisted in the event row.
dataJson string: The event payload as persisted (JSON).

Returns

UpcastedEvent: The effective type name and payload after upcasting. When no upcaster matches, the inputs are returned unchanged.

Exceptions

InvalidOperationException: The upcaster chain is cyclic.
