onResponse

public abstract void onResponse(@Nonnull
                                com.apollographql.apollo.api.Response<T> response)

Gets called when GraphQL response is received and parsed successfully. Depending on the ResponseFetcher used with the call, this may be called multiple times. #onCompleted() will be called after the final call to onResponse.

Parameters:

response - the GraphQL response

onFailure

public abstract void onFailure(@Nonnull
                               ApolloException e)

Gets called when an unexpected exception occurs while creating the request or processing the response. Will be called at most one time. It is considered a terminal event. After called, neither onResponse(Response) or #onCompleted() will be called again.

onStatusEvent

public void onStatusEvent(@Nonnull
                          GraphQLCall.StatusEvent event)

Gets called whenever any action happen to this GraphQLCall.

Parameters:

event - status that corresponds to a GraphQLCall action

onHttpError

public void onHttpError(@Nonnull

Gets called when an http request error takes place. This is the case when the returned http status code doesn't lie in the range 200 (inclusive) and 300 (exclusive).

NOTE: by overriding this callback you must call Response.close() on ApolloHttpException.rawResponse to close the network connection.

public void onNetworkError(@Nonnull
                           ApolloNetworkException e)
