Interface ProviderSignInInterceptor<S>

Type Parameters:

S - The service API hosted by the intercepted service provider.

public interface ProviderSignInInterceptor<S>

Listens for service provider sign in events. Allows for custom logic to be executed before and after sign in is performed via a specific service provider. Note that this interceptor only handles events during ProviderSignInController's flow. It does not handle events that take place in the case where ProviderSignInController redirects to the application-defined signup process. In that case, interceptors are not necessary and any post-signup logic can be performed using the connection carried in the ProviderSignInAttempt.
