Member Function Documentation

◆ clear()

void QgsFilterResponseDecorator::clear ( )

inlineoverridevirtual

Reset all headers and content for this response.

Implements QgsServerResponse.

Definition at line 75 of file qgsfilterresponsedecorator.h.

◆ data()

QByteArray QgsFilterResponseDecorator::data ( ) const

inlineoverridevirtual

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 77 of file qgsfilterresponsedecorator.h.

◆ finish()

void QgsFilterResponseDecorator::finish ( )

overridevirtual

Finish the response, ending the transaction.

The default implementation does nothing.

Reimplemented from QgsServerResponse.

Definition at line 44 of file qgsfilterresponsedecorator.cpp.

◆ flush()

void QgsFilterResponseDecorator::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()'. The default implementation does nothing.

Reimplemented from QgsServerResponse.

Definition at line 63 of file qgsfilterresponsedecorator.cpp.

◆ header()

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

inlineoverridevirtual

Returns the header value.

Implements QgsServerResponse.

Definition at line 57 of file qgsfilterresponsedecorator.h.

◆ headers()

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

inlineoverridevirtual

Returns the header value.

Implements QgsServerResponse.

Definition at line 59 of file qgsfilterresponsedecorator.h.

◆ headersSent()

bool QgsFilterResponseDecorator::headersSent ( ) const

inlineoverridevirtual

Returns true if the headers have already been sent.

Implements QgsServerResponse.

Definition at line 61 of file qgsfilterresponsedecorator.h.

◆ io()

QIODevice* QgsFilterResponseDecorator::io ( )

inlineoverridevirtual

Returns the underlying QIODevice.

Implements QgsServerResponse.

Definition at line 69 of file qgsfilterresponsedecorator.h.

◆ removeHeader()

void QgsFilterResponseDecorator::removeHeader ( const QString & key )

inlineoverridevirtual

Clear header Undo a previous 'setHeader' call.

Implements QgsServerResponse.

Definition at line 55 of file qgsfilterresponsedecorator.h.

◆ sendError()

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

inlineoverridevirtual

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.
