Constructors

ProjectionAttribute(string, string?)

Optional attribute used to adorn classes to configure a projection. The projection will have to implement IProjectionFor<TReadModel>.

public ProjectionAttribute(string id = "", string? eventSequence = null)

Parameters

id string

Optional identifier. If not specified, it will default to the fully qualified type name.

eventSequence string

Optional the name of the event sequence to observe. When not specified, the event sequence is inferred from the event types used in the projection definition.

Remarks

Initializes a new instance of ProjectionAttribute.

Properties

EventSequenceId

Gets the explicit event sequence identifier, or null if not specified.

public EventSequenceId? EventSequenceId { get; }

Property Value

EventSequenceId

Remarks

When null, the event sequence is inferred from the event types used in the projection definition. If all event types originate from the same event store (via EventStoreAttribute), the projection will automatically subscribe to the corresponding inbox event sequence.

Id

Gets the unique identifier for the reducer.

public ProjectionId Id { get; }

Property Value

ProjectionId
