Parâmetros

eventData
DbContextEventData

Informações contextuais sobre o DbContext que está sendo usado.

result
InterceptionResult<Int32>

Representa o resultado atual se houver um. Esse valor terá HasResult definido como true se algum interceptador anterior suprimisse a execução chamando SuppressWithResult(TResult). Esse valor normalmente é usado como o valor retornado para a implementação desse método.

cancellationToken
CancellationToken

Um CancellationToken a ser observado enquanto aguarda a conclusão da tarefa.

Retornos

Se HasResult for false, o EF continuará normalmente. Se HasResult for true, o EF suprimirá a operação que estava prestes a executar e usar Result . Uma implementação desse método para qualquer interceptador que não está tentando alterar o resultado é retornar o result valor passado.

Exceções

Se o padrão CancellationToken for cancelado.
