Methods

ThrowIfAnyMethodHasNonNullableCurrentReadModel(Type, Type, IEnumerable<Type>)

Throw if any reducer-shaped method on the type declares a non-nullable current read model parameter.

public static void ThrowIfAnyMethodHasNonNullableCurrentReadModel(Type reducerType, Type readModelType, IEnumerable<Type> eventTypes)

Parameters

reducerType Type

Reducer type to check.

readModelType Type

Type of the read model the reducer reduces to.

eventTypes IEnumerable<Type>

Known event types in the process.

Exceptions
