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.

Member Function Documentation
[virtual] EnginioReply::~EnginioReply()
Destroys the EnginioReply.
The reply needs to be deleted after the finished signal is emitted.
[signal] void EnginioReply::finished(EnginioReply * reply)
This signal is emitted when the EnginioReply reply is finished. After the network operation, use the isError() function to check for potential problems and then use the data property to access the returned data.
bool EnginioReply::isError() const
Returns whether this reply was unsuccessful. Returns true if the reply did not succeed.
bool EnginioReply::isFinished() const
Returns whether this reply was finished or not. Returns true if the reply was finished.
[signal] void EnginioReply::progress(qint64 bytesSent, qint64 bytesTotal)
This signal is emitted for file operations, indicating the progress of up or downloads. The bytesSent is the current progress relative to the total bytesTotal.
