Parâmetros
- command
- DbCommand
O comando.
- eventData
- CommandEventData
Informações contextuais sobre o comando e a execução.
- 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 normal desse método para qualquer interceptador que não está tentando alterar o resultado é retornar o result
valor passado, muitas vezes usando FromResult<TResult>(TResult)
