ApolloResponse

Represents a GraphQL response or an exception if no GraphQL response is received.

• data contains the parsed data returned in the response

• errors contains any GraphQL errors returned in the response

• exception contains an exception if a GraphQL response wasn't received

GraphQL responses can contain partial data, so it is possible to have both data != null and errors != null. An ApolloResponse may be in any of these states:

• exception == null && data != null && errors == null: complete data with no errors

• exception == null && data != null && errors != null: partial data with GraphQL errors

• exception == null && data == null && errors != null: no data, only GraphQL errors

• exception == null && data == null && errors == null: no data and no errors - while technically possible, this should not happen with a spec-compliant server

• exception != null && data == null && errors == null: no GraphQL response was received due to a network error or otherwise
