Class defining fcgi response.
QgsFeedback * feedback() const override
Returns socket feedback if any.
QMap< QString, QString > headers() const override
Returns the header value.
int statusCode() const override
Returns the http status code.
Base class for feedback objects to be used for cancellation of something running in a worker thread.

virtual void removeHeader(const QString &key)=0
Clear header Undo a previous 'setHeader' call.
virtual void truncate()=0
Truncate data.
virtual void flush()
Flushes the current output buffer to the network.
virtual QByteArray data() const =0
Gets the data written so far.
virtual void setHeader(const QString &key, const QString &value)=0
Set Header entry Add Header entry to the response Note that it is usually an error to set Header afte...
virtual void clear()=0
Reset all headers and content for this response.
virtual void finish()
Finish the response, ending the transaction.
virtual bool headersSent() const =0
Returns true if the headers have already been sent.
virtual void sendError(int code, const QString &message)=0
Send error This method delegates error handling at the server level.
virtual QIODevice * io()=0
Returns the underlying QIODevice.
virtual QString header(const QString &key) const =0
Returns the header value.
virtual void setStatusCode(int code)=0
Set the http status code.
Thread used to monitor the fcgi socket.
