Member Function Documentation

QByteArray QgsBufferServerResponse::body ( ) const

inline

Returns body.

Definition at line 139 of file qgsbufferserverresponse.h.

void QgsBufferServerResponse::clear ( )

overridevirtual

Reset all headers and content for this response.

Implements QgsServerResponse.

Definition at line 115 of file qgsbufferserverresponse.cpp.

QByteArray QgsBufferServerResponse::data ( ) const

overridevirtual

Gets the data written so far.

This is implementation dependent: some implementations may not give access to the underlying and return an empty array.

Note that each call to 'flush' may empty the buffer and in case of streaming process you may get partial content

Implements QgsServerResponse.

Definition at line 123 of file qgsbufferserverresponse.cpp.

void QgsBufferServerResponse::finish ( )

overridevirtual

Finish the response, ending the transaction.

Implements QgsServerResponse.

Definition at line 82 of file qgsbufferserverresponse.cpp.

void QgsBufferServerResponse::flush ( )

overridevirtual

Flushes the current output buffer to the network.

'flush()' may be called multiple times. For HTTP transactions headers will be written on the first call to 'flush()'.

Implements QgsServerResponse.

Definition at line 101 of file qgsbufferserverresponse.cpp.

QString QgsBufferServerResponse::header ( const QString & key ) const

overridevirtual

Returns the header value.

Implements QgsServerResponse.

Definition at line 52 of file qgsbufferserverresponse.cpp.

QMap<QString, QString> QgsBufferServerResponse::headers ( ) const

inlineoverridevirtual

Returns all the headers.

Implements QgsServerResponse.

Definition at line 66 of file qgsbufferserverresponse.h.

bool QgsBufferServerResponse::headersSent ( ) const

overridevirtual

Returns true if the headers have already been sent.

Implements QgsServerResponse.

Definition at line 57 of file qgsbufferserverresponse.cpp.

QIODevice * QgsBufferServerResponse::io ( )

overridevirtual

Returns the underlying QIODevice.

Implements QgsServerResponse.

Definition at line 77 of file qgsbufferserverresponse.cpp.

void QgsBufferServerResponse::removeHeader ( const QString & key )

overridevirtual

Clear header Undo a previous 'setHeader' call.

Implements QgsServerResponse.

Definition at line 35 of file qgsbufferserverresponse.cpp.

void QgsBufferServerResponse::sendError	(	int	code,
		const QString &	message
	)

overridevirtual

Send error This method delegates error handling at the server level.

This is different from calling setReturnCode() which let you return a specific response body. Calling sendError() will end the transaction and any attempt to write data or set headers will be an error.
