Constructor & Destructor Documentation

◆ QgsBufferServerResponse() [1/2]

QgsBufferServerResponse::QgsBufferServerResponse ( )

Definition at line 27 of file qgsbufferserverresponse.cpp.

◆ QgsBufferServerResponse() [2/2]

QgsBufferServerResponse::QgsBufferServerResponse ( const QgsBufferServerResponse )
delete

QgsBufferServerResponse cannot be copied.

Member Function Documentation

◆ body()

QByteArray QgsBufferServerResponse::body ( ) const
inline

Returns body.

Definition at line 140 of file qgsbufferserverresponse.h.

◆ clear()

void QgsBufferServerResponse::clear ( )
overridevirtual

Reset all headers and content for this response.

Implements QgsServerResponse.

Definition at line 112 of file qgsbufferserverresponse.cpp.

◆ data()

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 120 of file qgsbufferserverresponse.cpp.

◆ finish()

void QgsBufferServerResponse::finish ( )
overridevirtual

Finish the response, ending the transaction.

Reimplemented from QgsServerResponse.

Definition at line 79 of file qgsbufferserverresponse.cpp.

◆ flush()

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()'.

Reimplemented from QgsServerResponse.

Definition at line 98 of file qgsbufferserverresponse.cpp.

◆ header()

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

Returns the header value.

Implements QgsServerResponse.

Definition at line 49 of file qgsbufferserverresponse.cpp.

◆ headers()

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

Returns all the headers.

Implements QgsServerResponse.

Definition at line 67 of file qgsbufferserverresponse.h.

◆ headersSent()

bool QgsBufferServerResponse::headersSent ( ) const
overridevirtual

Returns true if the headers have already been sent.

Implements QgsServerResponse.

Definition at line 54 of file qgsbufferserverresponse.cpp.

◆ io()

QIODevice * QgsBufferServerResponse::io ( )
overridevirtual

Returns the underlying QIODevice.

Implements QgsServerResponse.

Definition at line 74 of file qgsbufferserverresponse.cpp.

◆ removeHeader()

void QgsBufferServerResponse::removeHeader ( const QString &  key)
overridevirtual

Clear header Undo a previous 'setHeader' call.

Implements QgsServerResponse.

Definition at line 32 of file qgsbufferserverresponse.cpp.

◆ sendError()

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.

Parameters
codeHHTP return code value
messageAn informative error message

Implements QgsServerResponse.

Definition at line 59 of file qgsbufferserverresponse.cpp.

◆ setHeader()

void QgsBufferServerResponse::setHeader ( const QString &  key,
const QString &  value 
)
overridevirtual

Set Header entry Add Header entry to the response Note that it is usually an error to set Header after data have been sent through the wire.

Implements QgsServerResponse.

Definition at line 38 of file qgsbufferserverresponse.cpp.

◆ setStatusCode()

void QgsBufferServerResponse::setStatusCode ( int  code)
overridevirtual

Set the http status code.

Parameters
codeHTTP status code value

Implements QgsServerResponse.

Definition at line 44 of file qgsbufferserverresponse.cpp.

◆ statusCode()

int QgsBufferServerResponse::statusCode ( ) const
inlineoverridevirtual

Returns the http status code.

Implements QgsServerResponse.

Definition at line 83 of file qgsbufferserverresponse.h.

◆ truncate()

void QgsBufferServerResponse::truncate ( )
overridevirtual

Truncate data.

Clear internal buffer

Implements QgsServerResponse.

Definition at line 126 of file qgsbufferserverresponse.cpp.
