Detailed Description

The EnginioReply class contains the data from a request to the Enginio database.

The reply, when finished, contains information received from the server:

  • Data - object, which is a result from an earlier request, see the data function
  • Network status - in case of a network problem, additional information can be accessed through: errorType, errorString, networkError
  • Backend status - a finished request is always associated with a backend status code, which is just an HTTP code, and it can be queried through backendStatus

The finished signal is emitted when the query is done.

See also EnginioClient.
